Characterization of dual-electrode Mach-Zehnder modulator based optical frequency comb generator in two regimes

摘要

Amplitude and phase characterization of the output from a dual-electrode LiNbO3 Mach-Zehnder modulator based ultra-flat optical frequency comb generator is investigated for well-known “in-phase” operation and a new “out-of-phase” regime. The out-of-phase regime may be realized with a single-electrode Mach-Zehnder modulator.
