摘要

A high-Q microwave photonic filter using a semiconductor optical amplifier (SOA)-based mode-locking fiber ring laser is proposed,analyzed and experimentally demonstrated.The proposed microwave photonic filter can realize a high-Q frequency response,it is compact without an optical source,and it can be easily tuned by adjusting an optical variable delay line in a ring cavity.A result with a Q-factor of about 236 and a rejection ratio of about 45 dB is obtained.The measured results and the theoretical estimations agree very well.
