- An SOA (Semiconductor Optical Amplifier) is a semiconductor element that amplifies light. Antireflective processing is applied on both facets of a semiconductor laser to eliminate the resonator structure. When light enters from outside the semiconductor, the light is amplified by stimulated emission.
SOA is used for amplifying an optical signal. SOAs are included in the optical transceiver modules used for communication between data centers to amplify the optical signal in the 1.3 um band used for Ethernet communication in order to compensate for transmission loss.
Anritsu provides SOA modules that have high optical gain of 15 dB or higher and a low noise figure of 7 dB or less. The polarization dependent gain is also 1.5 dB or less, which enables signal amplification with practically no problem. The module is a 6-pin compact package with an isolator and TEC (Thermo-Electric Cooler), and can be mounted on CFP/CFP2.
It also complies with Telcordia GR-468-CORE for extremely high reliability, as well as the RoHS directive.
