Abstract
The present disclosure provides a microcavity soliton microwave source based on reference cavity locking, comprising: a pump laser unit for providing pump laser; an auxiliary laser unit for providing auxiliary laser; a micro-ring resonant cavity for receiving pump laser and auxiliary laser to generate an initial soliton optical comb; an output unit for converting the input soliton optical comb into microwave and outputting; and a feedback loop unit for filtering out two preset comb teeth in the initial soliton optical comb, and then performing beat frequency with two reference lights locked in frequency by a reference cavity respectively to obtain a feedback signal; the feedback signal acts on the auxiliary laser unit, and finally realizes phase locking of the soliton optical comb and the reference cavity mode to reduce the phase noise of the output microwave.
