Paper Abstract

A novel label abstraction and erasion scheme based on a FP-SOA is proposed for all-optical separation of the bit-serial 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 and that only one device is needed. Using this scheme, label abstraction and erasion can be realized with the extinction ratio of 9.72 dB and 7.05dB, respectively. And the influence of pulse width ratio between the label and payload pulse on the extinction ratio is also investigated. We find that for a given case, there must be an optimized pulse width ratio to make the extinction ratio largest. It depends on working points of the label pulses and payload pulses in the gain curve.
