FBG Characterisation Device

This tender documentation is for the purchase of equipment that will be used in fabrication of fibre Bragg gratings. A fibre Bragg grating is an area within the core of an optical fibre that has a refractive index that changes periodically. The gratings are fabricated by exposing optical fibre to an interference pattern, generated from a UV laser beam, which is scanned and modulated to adjust the strength and phase of the periodic refractive index along the fibre length. The technique enables us to make optical devices with highly specific and customised spectral responses in both reflection…
