High-Spectral Efficiency Transmission Based on New Design of Optical Frequency Comb Generato
Recently, there is increasing interest in high-spectral efficiency (SE) optical superchannel transmission employing an optical frequency comb generator (OFCG) driven by a single semiconductor laser. This paper introduces a new configuration for OFCG suitable for this application which consists of series connection of a dual-parallel Mach-Zhender modulator (DP-MZM) and two electro-absorption modulators (EAMs). The proposed configuration is able to generate 62 comb lines, within 1 dB-flatness, separated by 25 GHz spacing. The use of the proposed comb in 64-channel WDM superchannel operating with 160Gbps dual-polarization 16-QAM signal per comb line is demonstrated by simulation over around 500 km transmission. The simulation is based on a commercial package, namely Optisystem ver. 15.
