Abstract
Cascaded semiconductor optical amplifier (SOA) gates using
polarization multiplexing technique (PMT) are experimentally
demonstrated for the first time. The penalty is smaller than 1 dB
after three SOA gates. Numerical simulation shows that cascaded
SOA gates operated at single-channel can endure some gain
polarization sensitivity (GPS) of the SOA, but, even a small GPS
will rapidly reduce the number of cascaded SOA gates operated at
multi-channels. Experiment shows that in addition to GPS,
four-wave mixing (FWM) will also affect the performance of SOA
gates when operated in a multi-channel system.
