A novel scheme for all-optical frequency multiplication/recovery based on the SOA ring cavity

A novel scheme for all-optical frequency multiplication/recovery based on the semiconductor optical amplifier (SOA) ring cavity is proposed and investigated numerically. The results show, for a 2.5GHz driving pulse train, it can be generated 5-25GHz repetition rate pulse trains with low clock amplitude jitter (CAJ), polarization independence and high peak power. Furthermore, the extraction of the clock signal from a pseudorandom bit sequence (PRBS) signal can be realized based on the proposed scheme.
