A novel scheme of SCM label erasure using FP-SOA

A novel label erasion scheme based on a FP-SOA is proposed for all-optical separation of the subcarrier multiplexing (SCM) label from payload and its performance is investigated by simulation. Fabry-Perot semiconductor optical amplifier (FP-SOA) is attractive not only due to simple fabrication without anti-reflection coating step but also due to its signal amplification capability and strong nonlinearity to perform all-optical label processing. Important features of this scheme are that it does not make use of any high-speed electronics. Using FP-SOA as optical SCM label eraser, more than 9db extinction ratio can be obtained. Meantime the payload can be amplified by more than 11dB. In this scheme, FP-SOA acts as a low-pass filter as while as an amplifier.
