We present recent implementations of microwave photonic filters using the following two technologies: InP-based MDR (microdisk resonator) on and coupled to a nanophotonic SOI waveguide and dynamic Brillouin gratings (DBGs) in polarization maintaining fibers (PMF). Quasi-linear and continuously tunable ~360° phase shifts have been experimentally obtained when considering radiofrequencies greater than 18 GHz using MDR. Besides, we have designed and experimentally demonstrated multi-tap MWP filters, based on dynamic Brillouin grating reflectors in polarization maintaining fibers, showing a FSR variation larger than 60% in a two-tap filter.
