摘      要：An approach to generate a flat optical comb with tunable comb spacing and adjustable comb number is *** the proposed approach,a Mach-Zehnder modulator（MZM）,being biased to generate two carrier-suppressed first-order sidebands,is cascaded with a phase *** two optical sidebands are then sent to the phase modulator to generate two identical,but frequency-shifted phase-modulated *** to the complementary nature of the two adjacent comb lines in the phase-modulated spectra,the overlapping of the two spectra would lead to the generation of a flat optical *** only the phase modulation index or the microwave power is needed to be adjusted,the system is easy to be implemented with tunable comb spacing and adjustable comb *** simulations are performed,and the approach is verified by an experiment.
