Abstract

In this paper, a simple, compact and robust refractive index sensor has been developed, which is constructed by twisting a pair of silica microfiber to form a coupling device. The transmission spectrum of the device is highly sensitive to the surrounding refractive index and the highest sensitivity of -1665nm/RIU (refractive index unit) can be obtained at the refractive index value of 1.3605 for the fibers with diameter of 2.1μm. The developed sensor device is easy to construct, of low cost and compatible with optical fiber system.
