Semiconductor optical amplifier SOA

Sep. 21, 2020

What is semiconductor optical amplifier

Semiconductor Optical Amplifier is a kind of optical amplifier, a device that amplifies optical signals. Can be used to increase data transmission power and extend transmission distance. Semiconductor optical amplifiers use semiconductor materials as gain media. It can amplify the power of small signal light without significantly reducing other optical indicators. It can be widely used in optical communication transmission systems and optical fiber sensing systems as preamplifiers, wavelength converters, high-speed optical shutters, etc.


The working principle of semiconductor optical amplifier

SOA is composed of active area and passive area, and the active area is the gain area. When the light signal passes through the active area. It causes these electrons to lose energy in the form of photons and return to the ground state. The excited photons have the same wavelength as the optical signal, thereby amplifying the optical signal.


The semiconductor optical amplifier (SOA) photoelectric module produced by WSEE can be used in the optical transmission system to increase the optical power of uplink data and extend the transmission distance. The high-speed all-optical amplification mode is transparent to the transmission protocol and suitable for high-speed signal amplification. Semiconductor optical amplifier series modules have built-in drive circuits and logic control circuits to monitor key information such as input/output optical power, amplifier temperature, module temperature and signal gain in real time. The module can be configured to work in automatic optical power control (APC) or automatic gain control (AGC) mode through the host computer. The product has the characteristics of simple structure, small size, mature production technology, low cost, long life, low power consumption, and easy integration with other optical devices.
