Abstract
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 20GHz, the extinction ratio ∼15dB, the bandwidth 2GHz, and the corresponding quality factor 10. The microwave output within the passband was varied efficiently by ∼27dB with the rate of ∼6.7dB/mW, while the wavelength tuning rate of the resonator was −0.02nm/mW.
