Cross-gain modulation in a semiconductor optical amplifier (SOA) is one of the simplest techniques for all-optical wavelength conversion. However, the finite gain recovery time of the semiconductor optical amplifier causes distortion and pattern depe

We report a novel technique that utilizes a single electroabsorption modulator (EAM) to perform simultaneous four-wave mixing (FWM) demultiplexing and all-optical timing extraction. The extracted timing, using fast cross-absorption saturation, is use

A single electroabsorption modulator (EAM) is utilized to perform subharmonic all-optical timing extraction from 160 Gb/s. The extraction technique is based on fast time-dependent loss saturation inside the EAM. The extracted timing is used for optic
