Abstract

Optical Whispering Gallery Mode (WGM) microresonators have become a powerful tool in fundamental physics as well as significant applications. Optical sensors based on WGM resonators have shown ultra-high sensitivity levels for various analytes. Among various kinds of WGM resonators, microbubble resonators (MBRs) are especially appealing as sensors, since the optical and fluidic elements are combined into a single component. We have developed a simple, rapid, and reliable packaging technique for silica microbubble resonators using 3-D printed packaged chips. The packaged MBR offer Q-factors at high as 106 with stability to environmental fluxes such as temperature. As an initial application, we demonstrate internal pressure sensing with our packaged MBR devices. The integration of both optical and fluidic components shows potential in a wide variety of field-based and point-of-care applications.
