The global optoelectronics industry has gradually come out of their "low" to enter the recovery period. China's optoelectronics industry is at a critical period, and gradually a complete industrial chain, industrial development will further speed increase. Photoelectric week at the Beijing International held, our specially invited academicians of China's optoelectronics industry analysis, hoping to further promote the healthy and rapid development of opto-electronics industry.
           Photonics is the basis and development of pillar industries
Opto-electronics industry is not only a vigorous development of pillar industries of the country, but also other traditional and new industry development.
Optical communication industry in recent years has turned the corner and a significant trend of recovery, China's optical communication system in the world market position and have a share, such as Huawei, ZTE and Fiberhome enterprises contracted projects at home and abroad, showing the strength of competition. FTTH has entered the technological breakthroughs and high-speed development period. However, domestic production capacity of optical fiber and cable has yet to be digested, including the structural design of devices and materials, optoelectronic devices, including the growth of independent R & D and engineering capabilities have the potential setback, optoelectronic devices industry is also significantly immature, still rely on the introduction of the key device, it should be caused by adequate attention.
Smooth development of optical storage industry, its assessment of the state or an old: China is recognized instead of power-producing countries. CD royalties related to the pain, to face up to self-innovation has become a classic textbook, however, called for a long time laser-based Blu-ray HD-DVD and other emerging markets have a great catch up with technology, but also to remain only in words, so far has yet to see a strong layout.
Light show by the flat panel display industry to replace the cathode ray display an irreversible trend, in the color TV and PC flat panel display market, PDP and LCD in terms of quality and price competition continues. LED full color LED display as a result of three primary colors to high-quality low-cost and full of vitality, OLED technology in full swing, has been shown in a small screen to play a role in the application. Use of high-power laser trichromatic color gamut to achieve large display is worthy of great importance to the new technical means, in the high-grade large-screen movie theater can be the first to be shown on the application, and the three primary colors of the high-power LED projectors and projector is expected to mini will not only enter into the family, carry and use with notebook computers can be expected.
Semiconductor energy-efficient lighting in the potential has been recognized in the field in our country, regardless of semiconductor lighting, landscape lighting, miner's lamp and other special applications, die and wafer production technology, the level of high-power chips, and even have the MOCVD equipment made considerable progress, standards and patent research have begun, in particular, silicon substrates, such as LED and phosphor with independent intellectual property rights aspects of the research and development, is surrounded by a breakthrough patented abroad, the success of the First World War, should be given a positive evaluation and continued support.
Now as "Eleventh Five-Year" national semiconductor lighting major projects have been initiated, but since last year, the international white-light LED technology and the rapid development of electro-optical conversion efficiency, we and the international community not only failed to narrow the gap continued to widen but to urge the Government, industry and the financial sector to give greater attention and more robust support for the semiconductor energy-efficient lighting for the country to make effective contributions.
       Optoelectronic Functional Materials R & D commercialization weak strong
Nonlinear optical crystal is an important feature of the photoelectric material information is one of photonics technology, laser technology, in particular, an important material foundation. Nonlinear optical crystal materials can be used for laser frequency conversion, expansion of the laser wavelength; used laser intensity modulation, phase; the realization of the holographic storage laser signal to eliminate the wavefront distortion of the self-pumped phase conjugation and so on. Therefore, the nonlinear optical crystal is a modern high-tech military technology and an indispensable key to the material. So far, with the market value of the nonlinear optical crystal are lithium niobate, potassium dihydrogen phosphate, potassium deuterium phosphate, lithium iodate, potassium titanium phosphate oxygen partial barium borate, boric acid three lithium niobate potassium, cesium borate, cesium lithium borate, and silver gallium sulfur, arsenic cadmium germanium, zinc phosphate, such as germanium. With the end of the last century the tide of the world's information technology and the rapid development of photonics technology, widely used, both at home and abroad on the optoelectronic functional crystal nonlinear optical crystal, especially the sharp increase in market demand. In 2005, the global market size of nonlinear optical crystal has reached 856.1 million U.S. dollars.
China's non-linear optical crystal in the industry has also made significant progress, the establishment of a number of specialized production and sales companies nonlinear optical crystal, LN, LT, KTP, LBO, BBO crystals have been achieved, such as commercialization, products not only meet the domestic needs, but also a large number of exports in some countries in Europe and America.
China is the invention of LBO, BBO, KBBF flux method to grow the first time can be the practical application of a large single crystal of the KTP, but in the commercialization of non-linear optical crystal is not in international competition advantage. This is mainly because the nonlinear optical crystal is related to the commodities market components form, and we will be crystal materials processed into components of the technology required is relatively backward, especially in pass smooth and high precision polishing anti-laser injury by the anti-film coating technology, the larger the gap with international standards. Preparation of high-tech devices in some areas, such as quasi-phase matching Preparation inverter, we also did not fully cross the border. Israel, Sweden, to buy my Shuo KTP optical chip, a L ¡Á W ¡Á H is 35mm ¡Á 35mm ¡Á 1mm chip of KTP, the price is 500 U.S. dollars, they get back into PPKTP (quasi-phase-matched KTP), even if the yield 50% can be made smooth for 5 pass 1mm ¡Á 2mm, length 20mm optical pass the PPKTP, this size converter PPKTP sell some of China's scientific research units, each is only 2300 U.S. dollars, worth 11,500 U.S. dollars, KTP is to buy our chips 500 U.S. dollars spent by 23 times!
It can be seen that in the future development of China's non-linear optical crystal, and promote the industrialization of the work, in addition to continued strong performance of the development of new nonlinear optical crystal, improve and perfect the existing nonlinear optical crystal, the need to develop nonlinear optical crystal device processing equipment, to strengthen the device processing capacity and improve the level of processing technology, as soon as possible, such as quasi-phase matching pieces Preparation inverter technology to optoelectronic devices to promote the advantages of nonlinear optical crystal materials in China the advantages of competition in the international market in order to win.
     Energy shortage is a new opportunity for opto-electronics industry
In recent years, the rapid development of opto-electronics industry, initially equipped with the foreign companies the ability to compete. However, the domestic opto-electronics industry is still faced with many challenges. First of all, with the exception of optical communication, the other relatively slow development of opto-electronics industry, such as optical storage, light display, light, light sensor, etc.; Secondly, a lot of opto-electronics industry in China is not a complete industrial chain, the added value of the largest scientific and technological content of the highest components often monopolized by foreign enterprises, independent innovation ability of enterprises to be further improved; third, research institutions and enterprises and the markets closely enough, there is no form to enterprises as the mainstay, the combination of technical innovation system. How to combine the status of China's scientific and technological development of opto-electronics industries, for building an innovation-oriented country to contribute to is that we need to think about.
On the needs of the market, the opto-electronics industry is mainly in the following aspects may be more room for growth: optical networks and optical access network, such as Fiber to the Home (FTTH); optical storage in the storage Blu-ray, optical holographic storage; light show The large-size LCD displays, OLED displays; semiconductor lighting and the use of solar cells; In addition, fiber-optic sensor, the medical field there are more room for growth.
Opto-electronics industry has experienced the climax of the last century, the beginning of this century low, and now it should be said that has returned to the normal development of the road. In fact optoelectronics industry in the economic, social and national security, many areas have a wide range of needs in building an innovation-oriented country in the process of the role of opto-electronics industry will become more and more come out.
Lack of social energy future, this is an opportunity for the development of opto-electronics industry. Flat panel display, semiconductor lighting to save energy on the very edge. In addition, with the improvement of living standards for high-definition, easy to carry, healthy low demand for the flat panel display is bound to gradually increase. Semiconductor lighting industry is the lighting of the green revolution, the industry will be rapid development. What is needed to achieve the main objectives are: first of all, to further enhance the luminescence efficiency, if we can reach 150lm / W, semiconductor lighting equipment into the tens of thousands of households will have a base; followed by the lower costs, if the semiconductor lighting and lighting equipment is the cost of traditional can at the same level, semiconductor lighting equipment will be a strong competitive advantage; final should also develop special LED lighting industry, the development of new areas.
     Hope that "war" and "Huawei" a few more
I would like to talk about my recent visit to Wuhan and Wuhan to meet the "China Optical Valley" of the core enterprise Fiberhome Technology Group and Huazhong University of Science and State Key Laboratory of some of the feelings.
Fiberhome Technology Group from Wuhan Post and Telecommunications Institute of Science and Technology developed the field of optical communication is a communication system, fiber optic cables and electro-optical device research, development, production and sales of scientific research and industrial entities. Through enterprise restructuring, the Group of Posts and Telecommunications, Wuhan Institute of Science and Technology of succession in the field of optical communication technology advantages of the deep, and carried forward in the industrialization of marketing and ability to grow by leaps and bounds. Their optical transmission system equipment and cable products are among the market share forefront of the domestic manufacturers, optical passive device and active device market share of domestic products have ranked first, a global supplier of optical components.
I visited the war situation in Science and Technology Group, I felt that, as China's optoelectronics business, they follow this path is right. I think the following is worthy of study.
First, from the Wuhan Research Institute of Posts and Telecommunications has grown up, have a good foundation, whether it is the theoretical basis for research or strength. Therefore, they are always new ideas and creativity into the outcome of the results into products. Second, emphasis on technology development, has a strong strength. Fiberhome Technology Group in the design and manufacture of opto-electronics technology, has been formed from material growth to the coupling packaging and testing part of the process system-wide. Third, attach importance to patents and software development. In ASIC design, has developed dozens of independent patent contains the core of the chip. Software development and maintenance personnel for more than the proportion of system equipment for more than half of the total number of R & D personnel. Also participated in the ITU standards. Fourth, to actively participate in international competition in the market, have a strong marketing capabilities, to build their own brands, vigorously implement the strategy of internationalization, constantly improve competitiveness in the international market.
Of course, this all can not be separated from people, can not be separated from the strong leadership as well as their development strategies.
I visit in Wuhan Huazhong University of Science and the Optoelectronics Laboratory, found that the results of their transformation and technology incubator done a very good job. Once a technology is mature, it immediately to the company, or the formation of the new company.
With them similar to the field of optical communication industry in China, Huawei also has a well-known groups, Huawei is very admirable, but I have not visited Huawei.
Therefore, the information I have on China's confidence in the development of opto-electronics, I sincerely hope that some of China's more like a war and Huawei as businesses.
     Combination is the only way for development by leaps and bounds
The information industry has become China's pillar industries, opto-electronics products in the information industry account for a large proportion of the 2004 statistics, China's display, color TV and video machines such as laser opto-electronics products in several of the production accounts for half of world output more than has been the formation of large industries, but the profit margins of these opto-electronics industry is very low, only a fraction of the foreign countries, showing a state of great and not strong.
In the "national long-term framework for the development of science and technology" to start, we should be promoting positive interaction with industrialization of the scientific concept of development under the guidance of the spirit of building an innovation-oriented countries the concept of the development of China's optoelectronics industry, and seize the photoelectron the rapid development of technology in upgrading the opportunity to find a breakthrough to improve China's optoelectronics industry's competitiveness.
Such as display technology from the last century since the 30's, after black-and-white display, color display, up to now the figures show that the basic solution to the high-definition video image acquisition, processing, storage, transmission and reproduction technologies, but it does not involve high color reduction issues, large color gamut coverage of the laser show the rapid development in recent years is likely to promote the show products to replace old ones, the formation of a new generation of display technology.
For the realization of China's independent development of opto-electronics industry, the Government's leading role is very important. Compatible in the international conditions, to increase their industrial competitiveness, at the same time step up across the development, implementation, and develop new markets, and the combination is the only way for development by leaps and bounds, universities and research institutes is the main body of knowledge innovation, technological innovation of enterprises are the main The two essential one, can not be balanced, long-term strategy for a decade, China's optoelectronics industry will be strong by the major development changes.
