Refractive Index Sensor Based On An Abrupt Taper Michelson Interferometer In a Single-Mode Fiber
A simple refractive index sensor based on a Michelson interferometer in a single-mode fiber is constructed and demonstrated. The sensor consists of a single symmetrically abrupt taper region in a short piece of single-mode ...
Single-Mode Fiber Refractive Index Sensor Based on Core-Offset Attenuators
Mach-Zehnder and Michelson interferometers using core-offset attenuators were demonstrated. As the relative offset direction of the two attenuators in the Mach-Zehnder interferometer can significantly affect the extinction ...
