Abstract
We propose and experimentally demonstrate novel photonic microwave notch filters using adjustable DGD elements. A notch rejection greater than 35 dB is obtained. The configuration is free from the problems of optical coherence interference and chromatic dispersion. The notch frequency is continuously tunable by adjusting the DGD value. The scheme can operate over a wide range of optical carrier frequencies and is free from the limitation of phase noise.
