With the trend of development of the Internet, optical fiber communication has become a major means of communication. Optoelectronic devices for optical fiber communication needs more and more types of requirements are getting higher and higher. Today to discuss the characteristics and trends of the optoelectronic devices.

A. High-speed, large capacity, high-power
With the rapid development of Internet, the increasing demand for bandwidth. Fully tap the single fiber transmission capacity has become business operators, equipment manufacturers and device suppliers, the main development direction one. Greater speed, capacity, power optoelectronic devices is the focus of investment by the major device suppliers.

B. Integration, miniaturization, low-cost
Optical fiber communication market competition is increasingly fierce, the communications equipment requirements of smaller and smaller, the interface board contains the interface increasing density, power consumption is getting smaller and smaller. Traditional discrete lasers and photoelectric detection tube-based program, no longer meet the requirements of modern communication equipment. In this case, the integrated high photoelectric one module and optoelectronic repeater is increasingly favored by the equipment manufacturer.

C. Cooling the light source
Laser production process to improve the performance of the laser chip, such as temperature characteristics, the modulation efficiency and so on have been greatly improved. The laser chips can no refrigeration conditions in a wide temperature range. Without refrigeration laser package process is relatively simple cooling laser, the volume is also smaller, lower price. The user, the use of no refrigeration lasers so that they save the cost of automatic temperature control circuit devices, board space and power consumption of about 2 watts.

D. Wavelength tunable lasers and optical switches based on microelectromechanical systems (MEMS)
Optical fiber communication link connection from the early and gradually to the development of optical transport network. Optical switch and wavelength tunable lasers will play a very important role in future optical transmission equipment.
