摘要：

Large scale integration of photonics devices requires low power consumption devices. In this paper, we demonstrate a low power consumption polymer/silica hybrid thermo-optic switch based on racetrack resonator. With the high index-contrast between SU-8 core, silica buffer and PMMA cladding, a compact racetrack resonator with a small bending radius of 120 mu m and a coupling length of 1765 mu m is fabricated through simple and low-cost contact lithography technology. An extinction ratio of 16.83 dB is achieved while the power consumption applied is 14.69 mW. The energy efficiency of the switch is 12.07 pm/mW. The rise/fall time the switch is 174 mu s/182 mu s.
