Optimization of Close-In Phase Noise for Microwaves Generated With Kerr Combs Using Brillouin-Assisted Pump Depletion

Optimization of Close-In Phase Noise for Microwaves Generated With Kerr Combs Using Brillouin-Assisted Pump Depletion

We report a method to improve the close-in phase noise performance of microwave signals generated using Kerr optical frequency combs. We propose a technique based on Brillouin-assisted pump depletion, and we show that the resulting phase noise close to the microwave carrier can be significantly lowe...
