A tunable ring resonator (RR) formed from SiSiO2 waveguides with an electro-optic polymer cladding is proposed with emphasis on the trade-off between the tuning voltage and ring radius. The ring resonator circuit combines the advantages of SiSiO2 and polymer technologies. The advantages of this hybrid ring design over previously proposed tunable silicon rings include an increased switching speed, from 5GHzto20to100GHz, single-polarity instead of dual-polarity voltage tuning and a voltage-independent quality factor. The hybrid design also displays a greater free spectral range (1.85nm instead of 0.1nm) and a wider tuning range (0.925nm instead of 0.05nm) and is further compatible with silicon devices. Moreover, the device has a high quality factor of 3.4×104.
