Optical information science and technology is a university undergraduate science and technology disciplines, belonging to the engineering electronic information science category. Discipline training goal is to have a solid basic knowledge of mathematics, physics, electronics and computers, systematic mastery of optical information processing technology, modern electronics technology and computer applications, basic skills, can be in the optical communications, optical information processing, and related electronic information science, computer science and other information technology fields, especially in the optoelectronic integration industry engaged in scientific research, product design and development, Production technology or management of the twenty-first century-oriented senior specialists.
Applications include:
Semiconductor optoelectronic materials: in China, for integrated circuits (IC) and solar cells monocrystalline silicon (Si) annual output of about 400 tons. GaAs single crystal for optoelectronic devices, InP single crystal for LEDs and LDs and GaP chip materials for red and green LEDs have been practical. Wide-band semiconductor materials such as GaN and SiC for blue LDs and blue and green LEDs are under development.
In terms of laser crystal materials: North China Institute of Optoelectronics Technology developed Nd: YAG crystal blanks performance indicators reached the international advanced level. The annual batch production capacity of YAG laser rods of Huabo Technology Co. is 3,000 rods. China has become a major producer and exporter of yttrium aluminate (YVO4) crystals. The Fujian Institute of Physical Structure of the Chinese Academy of Sciences has developed large-size YVO4 single crystals and processed them into polarized crystal devices.
In terms of nonlinear optical crystals: China developed barium borate (BBO), lithium borate (LBO) and other high-quality nonlinear optical materials, is the first of its kind in the international arena, used for laser light source in the visible region of the frequency conversion. For laser frequency doubling, optical parametric oscillation, electro-optical Q-tuning and acousto-optic, electro-optical devices of lithium niobate (LN) single crystal China's annual production capacity of about 10 tons.
Optoelectronic materials development focus on: high power, tunable, LD pumping and new wavelength laser crystals; ultra-high brightness (LED), semiconductor lasers (LD) with GaAs, Gap, GaN-based epitaxial materials, etc.; STN, TFT displays, liquid crystal materials, etc.; used for dense wavelength-division multiplexing system of the G.655 non-zero dispersion displacement fiber and large-size fiber optic pre-fabricated rod etc.
