Abstract

In this paper, we describe a fiber-optics-based system for the generation of optical frequency comb using amplified spontaneous emissions from a semiconductor optical amplifier (SOA) as signal source. The continuous-wave (CW) spectrum from the SOA ranges from 1480 nm to 1680 nm. A Solc-Sagnac birefringent interferometer filters the CW into a comb of discrete spectral lines with line spacing of 600 GHz, producing comb signals than span 182-230 THz.
