A short length of optical fiber that filters out a particular wavelength. Periodically spaced zones in the fiber core are altered to have different refractive indexes slightly higher than the core.

A growing number of enterprises around the world are now commercializing fibre Bragg grating sensors for sensing everything from temperature and pressure to vibration and strain. Duncan Graham ...

This means that if a waveguide or fibre containing a Bragg grating is exposed to the outside environment, then monitoring the wavelength of the reflected light allows sensing to be performed.
