摘要

A switchable microwave photonic filter (MPF) using a phase modulator (PM) and a silicon-on-insulator microring resonator (MRR) is proposed and demonstrated.By adjusting the polarization controller between the PM and the MRR,the filtering function of the MPF can be switched between a band-stop filter and a band-pass filter.In a proof-of-concept experiment,an MPF with a rejection ratio of 30 dB (or 15 dB) for the band-stop (or band-pass) response and a frequency tuning range from 9.6 to 20.5 GHz is achieved.
