✦ Synopsis

An integrated photonic microwave reconfigurable filter was proposed and realized incorporating a tunable polymeric ring resonator. Its passband could be shaped electrically by shifting the resonant peaks of the resonator via the thermo-optic effect. As for the achieved performance, the center frequency was 20 GHz, the extinction ratio $15 dB, the bandwidth 2 GHz, and the corresponding quality factor 10. The microwave output within the passband was varied efficiently by $27 dB with the rate of $6.7 dB/mW, while the wavelength tuning rate of the resonator was À0.02 nm/mW.

## Abstract A continuously tunable microwave photonic notch filter is proposed and experimentally demonstrated. This filter is based on the differential group delay generated by a high‐birefringence linearly chirped fiber Bragg grating. The tunability is realized by applying gradient tension to the
