## Abstract We demonstrate a widely tunable polymer add/drop reflection filter using doubleβring resonators with slightly different radii. The reflector proposed as an alternative to gratingβbased wavelengthβselective reflectors shows a wide tuning range of 42.3 nm using a small amount of current a
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 freque
