In this project, a novel refractive index (RI) sensor based on the abruptly tapered biconical fiber was proposed and demonstrated. The RI sensor is based on the theory of mode coupling in the tapered fiber. It has been shown that when a single mode fiber is tapered, the fundamental mode will be coup...
