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.

Conference Presentations are recordings of oral presentations given at SPIE conferences and published as part of the proceedings. They include the speaker's narration with video of the slides and animations. Most include full-text papers. Interactive, searchable transcripts and closed captioning are now available for 2018 presentations, with transcripts for prior recordings added daily.
