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.

Principle of Fiber Optic Resonant Ring Sensor
A ring resonator (RR) sensor is a type of optical sensor that is based on the principle of resonant light coupling in a ring-shaped WG. This sensor typically consists of a ring-shaped WG that is made from a high-refractive-index material, such as silicon (Si) . An optical ring resonator is a set of waveguides in which at least one is a closed loop coupled to some sort of light input and output. (These can be, but are not limited to being, waveguides.
