An approach for suppressing waveform distortion of SOAs by controlling the temperature on in-line optical amplifier systems

Semiconductor Optical Amplifier (SOA) has attracted attention as a key component in supporting large capacity transmission systems. However, SOAs cause waveform distortion depending on the carrier lifetime, which ranges from picoseconds to nanoseconds, and this degrades signal quality. Thus, we are investigating suppressing by controlling gain characters time changing temperature of in-line optical amplifier This paper reports that is suppressed setting lower within settable range, result evaluating dependence amplification with theoretically.
