Paper Abstract

Kerr frequency combs based on integrated microresonators are very attractive to microwave photonics for their compact size, broad spectrum, and high repetition rate. Promising applications include low-phase-noise microwave generation, radio over fiber transmission, signal processing, channelized receiver, etc. For microwave photonic applications, the power conversion efficiency, which means the ratio of the pump power converted to the comb lines, is a very important metric, because it is closely related to the optical-microwave conversion loss and noise figure of the microwave photonic link. In this talk, we discuss the mechanisms that limit the conversion efficiency and the configurations for highefficiency Kerr comb generation. An example of Kerr comb based microwave true-time-delay beamforming network is also introduced.
