Abstract

Integrated microwave photonic (MWP) front-ends are capable of ultra-broadband signal reception and processing. However, state-of-the-art demonstrations are limited to performing only one specific functionality at any given time, which fails to meet the demands of advanced radio frequency applications in real-world electromagnetic environments. In this paper, we present a major departure from the current trend, which is a novel integrated MWP front-end capable of simultaneous cascaded functions with enhanced performances. Our integrated MWP front-end can delay or phase-shift signals within the selected frequency band while simultaneously suppressing noise signals in other frequency bands, resembling the function of a conventional RF front-end chain. Moreover, we implement an on-chip linearization technique to improve the spurious-free dynamic range of the system. Our work represents a paradigm shift in designing RF photonic front-ends and advancing their practical applications.
