Suspended Chalcogenide Microcavities For Ultra-Sensitive Chemical Detection

Abstract

Here we report on the fabrication and characterization of air-clad on-chip chalcogenide microdisk cavities (Q=32,000) at wavelengths of 2.0-2.5 microns for infrared spectroscopy. In addition, we analyze a method of photothermal sensing that leverages high-thermal confinement in optical microcavities that is theoretically capable of achieving part-perbillion (ppb) level detection of trace gas molecules.
