We have proposed and experimentally demonstrated a tunable photonic microwave notch filter based on bi directional modulation of an optical intensity modulator and bi-directional reflection of a chirped fiber grating embodied in a fiber loop mirror in which a fiber delay line was inserted as tapping elements. A discrete and continuous tuning of the filter can be obtained by changing the length of a fiber delay line and by tuning the optical wavelength of a laser, respectively.
