Abstract

We have demonstrated what we believe to be the first chalcogenide glass racetrack microresonator using a complementary metal-oxide semiconductor-compatible lift-off technique with thermally evaporated As 2 S 3 films. The device simultaneously features a small footprint of 0.012 mm × 0.012 mm , a cavity Q (quality factor) of 10,000, and an extinction ratio of 32 dB . These resonators exhibit a very high sensitivity to refractive index changes with a demonstrated detection capability of Δ n As 2 S 3 = ( 4.5 × 10 6 ± 10 % ) refractive index unit. The resonators were applied to derive a photorefractive response of As 2 S 3 to λ = 550 nm light. The resonator devices are a versatile platform for both sensing and glass material property investigation.
