Photonic RF Channelization Based on Microcombs
arxiv(2024)
摘要
In recent decades, microwave photonic channelization techniques have
developed significantly. Characterized by low loss, high versatility, large
instantaneous bandwidth, and immunity to electromagnetic interference,
microwave photonic channelization addresses the requirements of modern radar
and electronic warfare for receivers. Microresonator-based optical frequency
combs are promising devices for photonic channelized receivers, enabling full
advantage of multicarriers, large bandwidths, and accelerating the integration
process of microwave photonic channelized receivers. In this paper, we review
the research progress and trends in microwave photonic channelization, focusing
on schemes that utilize integrated microcombs. We discuss the potential of
microcomb-based RF channelization, as well as their challenges and limitations,
and provide perspectives for their future development in the context of on-chip
silicon-based photonics.
