Abstract

A simple and feasible techniques for ultra-wideband (UWB) triplet pulse generation based on gain switching of self-seeded reflective semiconductor optical amplifier (RSOA) is proposed and demonstrated. The proposed system consisted of RSOA, erbium doped fiber laser (EDFA), two fiber Bragg gratings (FBGs), and balanced photo detector (BPD). The short pulse train which has a low timing jitters and pulse width was generated based on gain switching of RSOA. The generated optical triplet Gaussian pulse was well match the Federal Communications Commission (FCC) mask in frequency domain. Generated UWB triplet pulse has a fractional bandwidth of about 146% and pulse width of 293ps, respectively.
