A fiber Bragg grating (FBG) is a type of distributed Bragg reflector constructed in a short segment of optical fiber that reflects particular wavelengths of light and transmits all others. This is achieved by creating a periodic variation in the refractive index of the fiber core, which generates a wavelength-specific dielectric mirror. Hence a fiber Bragg grating can be used as an inline optical filter to block certain wavelengths, can be use
Fiber Bragg gratings are created by using an intense ultraviolet (UV) light-fringe pattern to inscribe the periodic variation of refractive index into the core of a photosensitive optical fiber.
Extrinsic fiber optic sensors use a multimode optical fiber to guide the light to the sensor and back to a receiver. At the sensor extremity, the light leaves the fiber,
