Optoelectronic technical papersIf the microelectronics technology promoted by computer, the Internet, such as optical fiber communication, the rapid development of information technology changed people's way of life, the emergence of knowledge economy, then with the development of information technology, large capacity optical fiber communication network construction, optoelectronic technology will play a more and more important role. The Commerce Department said: \"in the 90 s, the photon industry all over the world with a much higher speed than the microelectronics industry, who gain the initiative in the optoelectronic industry, who will be in the tip of the 21st century science and technology of the title\". Japan calls for monthly have similar comments: \"the representative of leading industry of the 21st century, the first is the optoelectronic industry, the second is information and communication industry, the third is the health and welfare industry...\" , you can assert that optoelectronic technology will promote human again after the microelectronics technology revolution of science and technology.theoretical basis, solid professional knowledge and skilled experiment skills, moral, intellectual, physical, all-round development of the scientific talent advanced optoelectronic technology, is particularly important. Make students have in optics, optoelectronics, laser science, optical communication technology, optical waveguide and photoelectric integration technology, optical information processing technology, computer application technology to carry out the innovative basic theory research and work in the design, development, application and management should have the theoretical and technical basis. Optoelectronics is refers to the light wave band, namely, infrared, visible light, ultraviolet and soft X-ray (1011 hz frequency range 3 X ~ 3 X 1016 hz or wavelength range 1 mm ~ 10 nm) band of electronics. Optoelectronic technology after 80 s, and its related technologies penetrating into each other in the 90 s, the technology and application has achieved rapid development, is playing a more and more important role in the social informatization.In CD technology, under the promoting of visible light in recent years, semiconductor laser diodes and leds got rapid development. Blue-green lightsemiconductor laser diode (LD) and blue-green semiconductor light-emitting diodes (leds), yellow orange visible laser diode and high brightness light yellow orange green light-emitting diodes (leds) have been commercialized. The future development needs to continue to solve improve brightness, lower prices, improve the service life with the rapid development of semiconductor technology, various types of photoelectric detector, such as the charge-coupled device, light position sensitive device, photosensitive array detector arises at the historic moment, such as have made great progress. Into the 90 s, the development direction of photoelectric detector in addition to the development of high-speed photodetector response, the focus is to develop the focal plane array of photoelectric imaging device. Improving infrared focal plane array technology, the infrared detection technology into the second generation. Currently, cost reduction is the key of the infrared detector is widely applied in the field of civil. The 21st century, the development direction of infrared focal plane array, one is based on the existing improve the resolution, the second is to develop multi-functional and intelligent problem such as focal plane array.Such as optical communication, optical information processing, optical computing technology development, combined with advances in materials science and technology of manufacturing, makes in a single structure or monolithic substrate integrated optics, optoelectronic and electronic components, forming has a single function or multi-function optoelectronic integrated circuit (OEIC) and integrated optics (IOC). At present, the commercialization of integrated optical modulator, switch and shunt apparatus and adopting integrated optics coherent communication system, optical fiber gyro and optical fiber laser doppler interferometer system, and used in optical fiber transmission test of monolithic integrated optoelectronic integrated circuits. Predicts 2020, the development of optoelectronic integrated circuit and integrated optics speed equal to the 1970 s of the microelectronics technology, multi-function integrated optical devices and optoelectronic integrated device series, integrated optical signal processing speed will reach 1 GHZ.Optoelectronic industry in China started relatively early in scientific research, also has a higher levels of the application, including the development of optical fiber communication especially fast. Applications in national defence also carry out earlier, such as shooting range with laser light, infrared, television and other equipment, as well as the infrared guidance device, the infrared thermal imager, laser range finder, light night, etc. But civil market development later, really can form a larger scale of production of the product. During the \"eighth five-year plan\" in China for some photoelectric device enterprise technical transformation, has set up a file in the \"five-year\" plan benefits. For example, 12 inches color LCD display screen has been put into production in 1996. Major national complete communication equipment 2.5 Gbps synchronous digital series (SDH) optical communication system, developed in 1997, success is now widely used in the construction of the national communication backbone.光电子技术论文如果说微电子技术推动了以计算机、因特网、光纤通信等为代表的信息技术的高速发展,改变了人们的生活方式,使得知识经济初见端倪,那么随着信息技术的发展,大容量光纤通信网络的建设光电子技术将起到越来越重要的作用。
