Fiber Bragg Grating
A fiber Bragg grating is an optical fiber with a periodic variation refractive index perturbation pattern inscribed in the core such that it diffract the optical signal in the guided mode at specific wavelengths into other core-bounded modes, cladding modes, or radiation modes
Huscent can provide FBGs used in optical communications, fiber lasers, optical sensors, etc. according to customer request.

The most common method for FBG fabrication is to expose a photosensitive fiber to an interference fringe pattern in UV light. This is usually accomplished by directing the output of an excimer laser through a phase mask .
The phase mask diffracts the incident laser light into various orders, which overlap and optically interfere with each other in the mask vicinity.
