Optoelectronic technology is promoting the transform of information age, and its key component, optoelectronic devices are bring along a new industry-optoelectronic industry.

Quantum well laser is the third milestone on the semiconductor laser developing history. It has been called as ideal laser diode due to its advantages in all-important parameters.

The breakthrough of quantum well optoelectronic devices in China have been done by Chinese Academy of Sciences, with support by Chinese National Natural Sciences Foundation and Chinese National High Technology Developing Plans. They have been employed in the fields such as optical fiber communication, optical storage, optical display etc. The research teams have expanded from pure academic organizations and universities to industry .This will open up the trails for industrialization of optoelectronic devices.

Recently, Optoelectronic industry in China has formed in embryo. Several companies, who run business in the field of optical fiber communication, have output value beyond one hundred million RMB per year. As to noncommunication optoelectronic devices, it is on the momentum of swift and violent development. To put key components such as visible lasers and high brightness LED into domestic production will bring along industry of the pick-up, loader, even DVD player and DVD ROM, and the industry of full color display, traffic lamp, vehicle lamp and solid white light lamp. Their output value beyond ten billion RMB per year can be expected.
