Abstract
Whispering Gallery Mode Resonators (WGMRs) are optical resonant cavities. By producing high Q-factor disks, the aim is to create miniature sensors which are able to track environmental variables (such as temperature) with high precision. Fabrication of the disks and coupling into the resonators is outlined and studied as well. A Q > 10^8 has been produced in this study, as well as coupling of over 60%. We were able to resolve temperature shifts down to about 500 nK, limited by electronic noise. Future outlooks are also mentioned.
