Optical Frequency Comb Generation for Broadband Microwave Photonics Receiver

Abstract

Microwave photonics approach for ultrabroadband signals processing has been investigated. In this case, optical filters select reference signals from optical frequency comb, which are used then for down-converting regions of the incoming RF spectrum using optical heterodyning technique. Then, low-rate electronic ADCs process photodetector's outputs enabling full mathematical recovery of the incoming signal.
