Abstract

High-capacity optical communication networks can be efficiently implemented using an optical multi-carrier generator (OMCG). A serial combination of three intensity modulators, such as the amplitude modulator (AM), single drive Mach-Zehnder modulator (SP-MZM), and AM, is suggested for the synthesis of the largest number of tones with a high tone to noise ratio (TNR) and the lowest amplitude difference (AD). The presented OMCG designs employ a single RF source; no additional fibre Bragg gratings or specialized techniques are used. The presented system is investigated for different radio frequencies (RF) and input powers in terms of AD and TNR respectively. Results revealed that 25 GHz RF frequency and 40 dB extinction ratio are optimal for the proposed system. Total 65 tones with a maximum bandwidth of 640 GHz, 0.96 dB AD, and the greatest TNR of 48.58 dB are offered by proposed system.
