Abstract

The fabrication and characterization of a packaged As2S3 microsphere resonator coupled to a tapered fiber using low refractive index UV-curable polymer is reported. Embedding provides an efficient means to remove the highest order whispering gallery modes in the microsphere resonator, thus cleaning the resonator spectrum. At wavelengths near 1549.5 nm, high-Q modes up to 1.8×105 can be efficiently excited in a 110 µm diameter chalcogenide microsphere via evanescent coupling from a 2 µm diameter tapered silica fiber. The device photosensitivity, useful for tuning, is still present and useable after the packaging process.
