We present and demonstrate all-optical clock recovery (CR) from the input single-and multiwavelength return-to-zero (RZ) data, using a single multiquantum-well Fabry-Perot semiconductor optical amplifier (FP-SOA) with no additional amplitude equalization measures. The influence of the FP-SOA facet reflectivity on the amplitude equalization of the recovered clock was numerically investigated. A stable 36.55 GHz optical clock with an extinction ratio of 11.0 dB and a root-mean-square timing jitter of 575 fs was extracted from the input, which consisted of 2(23)-1 pseudorandom binary sequences of RZ data. The presented scheme has the potential to perform CR from more than 100 Gbit/s of RZ data, and it has the advantage of wideband and parallel operation.
