Photonic RF and microwave channelizer based on a Kerr soliton crystal
micro-comb

Abstract
We report a 92 channel RF channelizer based on a 48.9 GHz integrated
micro-comb that operates via soliton crystals, together with a passive
high-Q ring resonator that acts as a periodic filter with an optical 3dB
bandwidth of 121.4 MHz. We obtain an instant RF bandwidth of 8.08 GHz
and 17.55 GHz achieved through temperature tuning. These results
represent a major advance to achieving fully integrated photonic RF
spectrum channelizers with reduced low complexity, size, and high
performance for digital-compatible signal detection and broadband analog
signal processing.
