Fiber Bragg grating demodulation module
It uses a scanning narrow-band semiconductor laser as light source to perform high-resolution fiber grating demodulation in the range of 40nm. 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. In all these applications, a way to discriminator with poor characteristics. Here, we present a simple, compact, and robust technique featuring high linearity over. Fibre Bragg grating (FBG) sensors are used to measure various quantities such as temperature, stress, vibrations, pressure, or refractive index. The characteristic feature of these sensors is that the position of the spectrum changes due to the action of a particular physical quantity.

Fiber Bragg Grating Compensation Method
A new method of packaging a fiber Bragg grating for temperature compensation using a symmetrical passive support consisting of two materials with different coefficients of thermal expansion was proposed. In a fiber Bragg grating, the refractive index inside the core changes in a period fashion along the grating length. Because of this feature, the grating acts as an optical filter. More specifically, it develops a stop band in the form of a spectral region over which most of the incident light is. A unique dispersion compensation system for a long-haul transmission system with a 5 Gbit/s data rate for each channel has been devised in this paper employing Fiber Bragg Grating (FBG) and Dispersion Compensation Fiber (DCF). The performance of dispersion compensation is evaluated using both. Theoretical and experimental investigation of a technique for creating a package for the passive temperature compensation of a fiber Bragg grating is presented.
