Abstract

An efficient method for simultaneous optical pulse multiplication and shaping is first proposed that is based on a triply sampled spectral filter utilizing a fiber Bragg grating. The proposed method enables efficient generation of an optical pulse train with a large multiplication factor and an arbitrary intensity profile. As examples, pulse trains with a repetition rate of 225 GHz and either a flat-top or triangular pulse waveform are numerically demonstrated, generated from a 1-GHz transform-limited Gaussian pulse train.
