Relative Humidity Sensor Based on Microfiber Loop Resonator

Relative Humidity Sensor Based on Microfiber Loop Resonator

A novel relative humidity (RH) sensor based on a microfiber loop resonator (MLR) is proposed and experimentally demonstrated. As refractive index of the microfiber in the MLR is modified by environmental humidity, resonant wavelength of the MLR changes with RH level. By detecting this wavelength shi...
