Wavelet-Based Demodulation of Multimode Etched Fiber Bragg Grating Refractive Index Sensor

Wavelet-Based Demodulation of Multimode Etched Fiber Bragg Grating Refractive Index Sensor

Etched fiber Bragg grating (EFBG)-based sensors are used as evanescent field sensors for refractive index detection. When the fiber thickness is thin and the refractive index sensitivity increases, the number of propagating modes increases, resulting in a spectral enlargement that complicates the in...
