Abstract

A new microwave photonic notch filter structure is presented. It is based on a remodulation concept, in which the second modulation is frequency selective. Results are presented for the new structure, which show a sharp narrow notch with a notch 6dB bandwidth of 63kHz and a notch depth of 44dB, a wide passband, and coherence-free operation with no phase induced intensity noise.
