Abstract

Normal group velocity dispersion mode-locked optical frequency combs are provided on-chip. On-chip coherent frequency comb generation includes pulses showing temporal durations of about 74 fs. Pump detuning and bandpass filtering are provided for stabilizing and shaping the pulses from normal group velocity dispersion microresonators.
