摘要

An integrated microwave photonic notch filter with improved noise figure is proposed, which is enabled by using a microwave photonic spectral shaper to shaping the amplitude and phase of the modulated optical spectrum. In the experiment, the notch filter exhibits a deep rejection of 66 dB, and an improved noise figure of 29.5 dB, which is reduced by 7.8dB.
