Abstract

In this paper, a broadband microwave photonic channelized receiver based on optical frequency comb (OFC) injection locking technology is illustrated. The simulation results show that, with more than 80 comb lines generated from OFC, this receiver enables channelized scanning and reception of broadband signal up to 40 GHz with instantaneous bandwidth of 1 GHz. Meanwhile, the channels selected using optical injection locking (OIL) technology, perform high gain and low phase noise with suppression ratio between the selected comb line and other comb lines is 28.7 dB. Due to OIL technology, the wideband tunability of this receiver would not depend on the optical filter or demultiplexer, and the band limitation and operation resolution introduced by optical components are broken through. The OIL technology also lead to the architecture of receiver more compact and feasible in practical.
