Flat frequency comb generation based on Mach-Zehnder modulator and phase modulator

A method to generate flat optical frequency comb is proposed and demonstrated which is based on Mach-Zehnder modulator and phase modulator cascade. Utilizing this method, we have analyzed flat optical frequency comb generation in the condition of different RF driving voltages. We also illustrate and correct the optimal operation condition for generating flat optical comb lines through the modulators.
