WHISPERING GALLERY MODE RESONATORS FOR SENSING APPLICATIONS

摘要

Sensing apparatuses and method of making the sensing apparatuses are disclosed herein. In some variations, a sensing apparatus can comprise at least one optical waveguide, and at least one whispering gallery mode (WGM) resonator (1602a-c) configured to propagate a set of WGMs, where the WGM resonator (1602a-c) communicates to the at least one optical waveguide (1601a-c) a set of signals corresponding to the set of WGMs. In some variations, a polymer structure may encapsulate the at least one WGM resonator and/or the at least one optical waveguide. Furthermore, in some variations, the WGM resonator(s) may have one or more selectable modes with different bandwidth and sensitivity for sensing, which may, for example, enable tailoring the sensing apparatus to specific applications having certain bandwidth and/or sensitivity requirements.
