An Ultrasensitive Long-Period Fiber Grating-Based Refractive Index Sensor with Long Wavelengths
The response of a novel long-period fiber grating (LPFG) with a period of 180 µm to a surrounding refractive index (RI) was investigated. The results displayed that, with the increase in RI of the surrounding media of cladding glass in the grating region, the resonant peak located at 1336.4 nm in th...
