Flexible Tuning Optical Frequency Combs via Parametric Seeding in Microresonators With Normal Dispersion

Abstract

We propose a novel method to flexibly tune the optical frequency combs generated in normal-dispersion microresonators based on parametric seeding. The pulse duration could be adjusted in the range of 0.7-3.076 ps by changing the seeding power from 1 to 5 mW, and the repetition rate could increase N times by setting the seeding frequency at N times free spectral range away from the pump.
