温度センシング用シリカトロイド微小光共振器の実装技術

抄録

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.
