Abstract

A simple and stable OFC generating system based on cascaded phase modulators is proposed. As there is no bias drift problem in phase modulator, the cascaded phase modulators based OFC generating system can achieve high amplitude stability only by adjusting the amplitude of the RF signal. The performance of the proposed structure is analyzed by numerical simulation, where 5, 7, 9, 11 OFCs are generated with flatness of 0.64 dB, 0.93 dB, 2.45 dB and 3.19 dB respectively. In addition, a proof-of-concept experiment was also set up, where 5, 7, 9 OFCs were generated with flatness of 0.593 dB, 2.356 dB and 3.924 dB respectively.
