A tunable polymer waveguide ring resonator is proposed and demonstrated for microwave photonic filtering. The ring resonator consists of a Mach–Zehnder interferometer (MZI) as the tunable coupler and two micro-heaters as the thermo-optic phase shifters. It was fabricated with inorganic–organic hybrid optical material polysiloxane-liquid series by a novel and simple UV-soft selective imprint technique...

An optical waveguide ring based notch filter was designed and fabricated with polymer PSQ-Ls for microwave photonic signal processing. The waveguide ring consists of a Mach-Zehnder interferometer (MZI) as the tunable coupler and two micro-heaters as the thermal-optic phase shifters. The coupling states, over-, critical- and under-coupling, were obtained with the phase shifter on the arm of MZI and...
Integrated waveguide based microwave photonic signal processing technology is promising and attractive for its advantages to bring down volume, weight and power consumption of equipments compared with discrete optical devices. In this paper polymer waveguide ring resonators fabricated with a novel ultraviolet-based soft-imprint technique are presented. Their filtering responses for microwave photonic...
