Abstract

A compact microfiber sensor is implemented with the twist of a continuous rectangular microfiber. The structure can exhibit extremely-high sensitivity of around 24,373nm per refractive-index unit and temperature stability of better than 0.005nm/oC, implying a great suppression of cross-sensitivity. Thia sensor is featured with compact size, high sensitivity, easy fabrication, robustness, and low connection loss with all-fiber system.
