A Refractive Index Sensor Based on the Resonant Coupling to Cladding Modes in a Fiber Loop
We report an easy-to-build, compact, and low-cost optical fiber refractive index sensor. It consists of a single fiber loop whose transmission spectra exhibit a series of notches produced by the resonant coupling between the fundamental mode and the cladding modes in a uniformly bent fiber. The wave...
