title: Self-assembled on-chip spherical-cap-shaped microresonators for high sensitivity temperature sensing.
abstract: In this paper, on-chip spherical-cap-shaped microresonators made from self-assembled UV-curable adhesive are proposed and demonstrated for high sensitivity temperature sensing. We observe the whispering-gallery mode resonances in these spherical-cap-shaped microresonators, and investigate the wavelength shifts of the resonance peaks as a function of both input power and temperature. The resulting devices with various diameters offer a high sensitivity of 0.14-0.22 nm/°C for temperature sensing.
