Abstract
Ultra-high-quality, whispering-gallery-mode (WGM) optical micro-resonators provide an unprecedented capability to trap light in a highly confined volume, smaller than a strand of human hair. A beam of light can travel the boundary of a WGM resonator over 106 times, significantly enhancing light-matter interactions for a variety of sensing applications. Our group has leveraged WGM sensors for a wide array of applications, including the detection of infrared light, gas sensing, photo-acoustic imaging, and nanoparticle detection and sizing. We have also developed a new hand-held microresonator platform that can be combined with commercial devices such as drones, as well as a fiber-based, WGM microprobe sensor.
