Abstract

Modern optical networks employ hundreds of lasers that fill up the limited bandwidth. Each laser generates a channel and each channel is separated by a spectrally inefficient region of space called a guard band. Optical frequency comb sources (OFCS), can potentially reduce or eliminate the use of these guard bands by creating coherent superchannels with a precise and stable frequency. In this paper we demonstrate a monolithically integrated comb source which is integrated with a filter with the intent to be used as a de-multiplexer.
