Phase noise analysis of an optical frequency comb using single side-band suppressed carrier modulation in an amplified optical fiber loop

Abstract

Coherent optical two-tone generation using an optical frequency comb generator based on an amplified optical fiber loop is successfully demonstrated. The observed phase noises in the 100-GHz band are less than -80dBc/Hz at 1MHz. This method is suitable for high-speed radio communication based on advanced modulation techniques.
