Guide Fibre Bragg grating technology
The Bragg grating acts like a mirror which only reflects one very precise wavelength (colour). When the optical fibre is strained or when its temperature changes, the reflected wavelength varies proportionally.

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
