Fiber Bragg Grating Low-Frequency Demodulation System
A demodulation algorithm is vital for a fiber Bragg grating (FBG) sensing system. In this paper, a novel demodulation algorithm based on the variable-step-size method and cross-correlation algorithm is proposed to demodulate the wavelength of an FBG. The characteristic feature of these sensors is that the position of the spectrum changes due to the action of a particular physical quantity. Determining the wavelength shift is the most important issue in precise measurements of.

Single-mode fiber long-period fiber grating
Long-period fiber gratings (LPGs) are applied in order to couple light between core and co-propagating cladding modes in single-mode optical fibers. For these applications, fibers with a high numerical aperture (i., fibers with highly germanium (Ge)-doped fused silica fiber. In essence, a long period fibre grating (LPFG) is an all-fibre device with wavelength dependent loss. The LPG exhibits large peak transmission attenuation of 30. The coupling from the guided mode to cladding modes is wavelength dependent so we can obtain a spectrally selective loss.
