Relative Humidity Sensor Based on No-Core Fiber Coated by Agarose-Gel Film

Relative Humidity Sensor Based on No-Core Fiber Coated by Agarose-Gel Film

A relative humidity (RH) sensor based on single-mode–no-core–single-mode fiber (SNCS) structure is proposed and experimentally demonstrated. The agarose gel is coated on the no-core fiber (NCF) as the cladding, and multimode interference (MMI) occurs in the SNCS structure. The transmission spectrum...
