Optoelectronic Industry

China Economic Times
As we all know, the 21st century is the information economy, information industry will become a pillar industry. In the United States in 1995 and 1998 the information industry accounted for 8% of U.S. GDP, but its contribution to U.S. real economic growth rate of 35 % reported in 2006 that nearly half of the nation's labor force will be employed in the information industry. The development of information industry, but with the development of photonics technology is closely linked.
Director, Institute of Semiconductors, Chinese Academy of Sciences, researchers Feng Songlin said that if computer-driven micro-electronics technology, the Internet, fiber optic communications, as represented by the rapid development of information technology has changed people's way of life, making the knowledge economy began to take shape , then with the development of information technology, high-capacity optical fiber communication network construction, opto-electronics technology will play an increasingly important role. Optoelectronics Industry U.S. Department of Commerce said: "90 years, the world's photonics industry than the microelectronics industry much higher speed of development, who made the initiative in the optoelectronics industry, whoever will be cutting-edge technology in the 21st century, he won the contest. "Japan's" voice "magazine has a similar comment:" 21st Century with a sense of leading industry representatives, The first is the optoelectronics industry, the second is the information and communication industry, the third is the health and welfare industry ... ... ", can say, photonics technology will continue to promote human again after the microelectronics revolution in science and technology.
He said, optoelectronic devices and components are widely used in long distance and large-capacity optical fiber communication, optical storage, optical display, optical interconnection, optical information processing, laser processing, laser medical and military weapons and equipment, is expected in future optical computing will play a important role.
The rapid development of photonics technology world
Chinese Academy of Engineering Wu He Quan said that the current optical fiber communication technology much faster than the original of people expected, optical fiber has become the communication network an important transmission medium in the world today there are about 60% of the communications business by the optical fiber transmission, to the late 20th century to reach 85%. However, the overall level of the current optical fiber communication, it is still in its infancy, the great potential of optical fiber communication has not been fully developed. At present, a variety of new technologies emerging, dense wavelength division multiplexing (DWDM, with a optical fiber to transmit multiple signals of different wavelengths of light to increase the transmission capacity of a single fiber), erbium-doped fiber amplifier technology (EDFA, optical signals can be directly amplified, with a high output power, noise, gain bandwidth, etc.) have been breakthrough and be widely used. Now DWDM systems and optical transmission equipment, optical technology, the proportion will increase from less than 10% over the past 90%. a new, without any change in the light optical communication - - "All-optical communication", due to wavelength division multiplexing technology and erbium-doped fiber amplifier technology advances, are becoming increasingly mature, will be across the Pacific and the Atlantic on the first use of a communication system, which brought the global communications industry booming life. this is the providing support for semiconductor optoelectronic devices and components. optoelectronic devices and technology has become a fast growing, large optoelectronics industry, the development of the national economy plays an increasing role. Optoelectronics Industry Development Association estimates the United States , 2003, the optoelectronics industry output will reach 200 billion U.S. dollars.
Feng Songlin that, Internet applications, the rapid growth of the telecommunications backbone network bandwidth, increasing the demand made, to meet the demand, people can lay more fiber, or a single light by increasing the information carrying capacity (now Backbone 2.5Gbps, respectively, and can work in 10Gbps, 40Gbps and presentation of existing equipment). but mostly rely on the development of the method is wavelength division multiplexing technology to increase the large ones of light through optical fiber (optical wavelength division multiplexing of the experimental record has reached 2.64Tbps). WDM technology commonly used for the optoelectronic devices and components to provide a broad, fast-growing market. unlimited strategy's report said: "signal transmission 1.31μm and 1.55μm laser market to reach 1999 1.3 billion, an increase over 1998, 23%; 1.48μm signal amplification laser market share in 1999 reached 1.6 billion U.S. dollars, an increase over 1998, 33%; 980nm laser signal amplification with sales of 2.9 billion U.S. dollars, up 121% from last year . the laser market share reached 1.8 billion U.S. dollars in 1999, is expected to reach 30 billion in 2003 dollars.
