Abstract

We propose and demonstrate experimentally an optical-pulse-train generator based on Fourier synthesis of four-wave mixing sidebands generated from semiconductor optical amplifiers. The amplitudes and the phases of four frequency components are optimally adjusted by an optical-transfer-function generator, which consists of a pair of diffraction gratings, three pairs of lenses, and liquid-crystal spatial light modulators. From this generator a 1.8-ps pulse train at a repetition rate of 113 GHz near the $1.5-\mathit{\mu }\mathrm{m}$ range is successfully generated.
