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.
An SOA (Semiconductor Optical Amplifier) is a semiconductor element that amplifies light. ... When light enters from outside the semiconductor, the light is amplified by stimulated emission. SOA is used for amplifying an optical signal.
A simple theory for the crosstalk in multichannel wavelength-division multiplexing (WDM) communication systems caused by the cross gain saturation in semiconductor optical amplifier (SOA) is developed.
We have demonstrated an all-optical S- to C/L-band wavelength up-conversion scheme for non-return-to-zero data using an optically pumped semiconductor optical amplifier (SOA). The 1480-nm input signal directly pumps the SOA and modulates its gain.
SOA optical amplifiers use the semiconductor as the gain medium, which is designed to be used in general applications to increase optical launch power to compensate for the loss of other optical devices.
