Abstract

We report the first integrated tunable microwave photonic notch filter based on on-chip stimulated Brillouin scattering. The notch filter has a high-resolution with 3-dB and 6-dB bandwidths of 126 MHz and 78 MHz, respectively. The filter has a notch depth of 20 dB, and the notch frequency can be continuously tuned over a range of 2 8 GHz, which is limited only by the current measurement setup.
