Abstract

Recently, there has been great interest in the use of microfiber resonators as optical sensors [1] and micro-optical devices [2] due to their compactness, robustness, high Q-factor and low-loss. In particular, temperature sensors exploiting the thermally-induced resonance wavelength shift have potentially high sensitivity, fine resolution and large operating temperature range. Here, we report on the theoretical and experimental analysis of such a sensor based on a microcoil resonator (MCR).
