Abstract

We demonstrate an integrated microwave photonic filter (MPF) with in situ programmability based on two-soliton microcomb. The relative angle of the two solitons can be arbitrarily tuned from 11° to 180° by the avoided mode crossing (AMX) which is controlled by a double ring resonator structure. The passband frequency of the proposed RF filter can be consequently tuned from 0.5GHz to 9 GHz.
