Silica toroid microcavities is an ideal platform if we want to obtain high sensitivity and small device size
simultaneously. However, it requires precise alignment of a tapered optical fi ber in order to couple light
into the microcavity. In this study we report on the packaging of a silica toroidal microcavity with an
input-output tapered optical fi ber, which enable us to make this device portable and use for practical
applications. The obtained Q of the packaged device is 1.7×106, and we performed thermal sensing by
using this device.
