Observation of modulation instability Kerr frequency combs in a fiber Fabry-Perot resonator

We report the experimental observation of a modulation instability induced Kerr frequency comb in an all fiber Fabry-Perot resonator. We fully characterized, in intensity and phase, the frequency comb using a commercial 10 MHz resolution heterodyne detection system to reveal more than 125 comb teeth within each of the modulation instability sidelobes. Moreover, we were able to reveal the fine tempo-ral structure in phase and intensity of the output Turing patterns. The experimental results are generally in good agreement with numerical simulations. (c) 2023 Optica Pub-lishing Group

Automated summary

We observed a Kerr frequency comb induced by modulation instability in an all fiber Fabry-Perot resonator. The frequency comb was fully characterized using a commercial 10 MHz resolution heterodyne detection system, revealing more than 125 comb teeth within each of the modulation instability sidelobes. We also discovered the fine temporal structure in phase and intensity of the output Turing patterns. The experimental results generally agree with numerical simulations.
