“…This is clearly undesirable if such resonators are to be used in larger PICs. Resonators that can be tuned post-fabrication have been reported, including devices with MEMs actuated [16] and thermally controlled Mach-Zehnder (MZ) coupling sections [17]. However, these devices exhibit large footprints, and in the case of the MEMs actuators, the fabrication of waveguide membranes creates structures that are extremely sensitive to environmental factors.…”

A compact silicon ring resonator is demonstrated that allows simple electrical tuning of the ring coupling coefficient and Q-factor and therefore the resonant enhancement of on-chip non-linear optical processes. Fabrication induced variation in designed coupling fraction, crucial in the resonator performance, can be overcome using this post-fabrication trimming technique. Tuning of the micro-ring resonator across the critical coupling point is demonstrated, exhibiting a Q-factor tunable between 9000 and 96000. Consequently, resonantly enhanced Four Wave Mixing shows tunable efficiency between −40 dB and −16.3 dB at an ultra-low on-chip pump power of 0.7 mW .

“…The tunable waveguide ring filter was fabricated with inorganic-organic hybrid optical material named as polysiloxane-liquid series (PSQ-Ls) developed in our group [33]. The PSQ-Ls material has large TO coefficient (dn/dT) with the potential to decrease the power consumption for tuning [34]. Its UV-curable and liquid properties permit the waveguide to be fabricated with the UV-soft imprint technique [35], which simplifies the fabrication process and reduces the cost.…”

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. The coupling conditions, over-, critical-and under-coupling, were obtained with the microheater on the arm of MZI and the maximum notch depth of about 18 dB was achieved. The resonant wavelength was also tuned with the micro-heater on the ring waveguide. The dispersion induced power fading of radio over fiber link was overcome by the tunable ring resonator with its notch filtering function.Index Terms-Microwave photonics, notch filter, polymer waveguide, ring resonator, tunable coupler, UV-soft imprint.
