Optical information science and technology is a major of undergraduate science and engineering, which belongs to engineering electronic information science. The goal of discipline training is to have a solid basic knowledge of mathematics, physics, electronics and computer, systematically master the basic skills of optical information processing technology, modern electronic technology and computer application technology, and be able to engage in information technology fields such as optical communication, optical information processing, related electronic information science and computer science, especially the scientific research, product design and development, production technology or management of integrated optical electromechanical computing industry.

The application fields mainly include:

In semiconductor photoelectric materials: In China, the annual output of monocrystalline silicon (Si) used in integrated circuits (ic) and solar cells is about 400 tons. GaAs single crystals for optoelectronic devices, InP single crystals for LEDs and LD, and GaP chip materials for red and green LEDs have been put into practical application. Wide band gap semiconductor materials such as blue LD, blue-green LED, GaN and SiC are under development.

In terms of laser crystal materials, the performance index of Nd:YAG crystal blank developed by North China Institute of Optoelectronic Technology has reached the international advanced level. Huabo Technology Co., Ltd. has an annual production capacity of 3,000 YAG laser rods. China has become a major producer and exporter of yttrium vanadate crystals. Fujian Institute of Structure has developed a large-size YVO4 _ 4 single crystal and processed it into a polarizing crystal device.

In terms of nonlinear optical crystals, high-quality nonlinear optical materials such as barium metaborate (BBO) and lithium triborate (LBO) developed in China are the first in the world, which are used for frequency conversion of laser light sources in the visible region. The annual output of lithium niobate (LN) single crystal China for laser frequency doubling, optical parametric oscillation, electro-optic Q-switching, acousto-optic and electro-optic devices is about 10 ton.

The development of optoelectronic materials focuses on: high power, tunable, LD pumped and new wavelength laser crystals; GaAs, Gap and GaN-based epitaxial materials for ultra-high brightness (LED) and semiconductor laser (LD); STN, liquid crystal materials for TFT display, etc. G.655 non-zero dispersion-shifted optical fiber and large-size optical fiber preform for dense wavelength division multiplexing system.
