Long fibre grating characterisation using low coherence reflectometry
At Conference on Lasers and Electro-Optics (CLEO Europe), Germany.

Optical fibre dispersion compensation, and distributed fibre sensors, make use of long fibre gratings. Their reflectivity and time delay are usually characterised as a function of wavelength using an expensive tunable laser. We have recently achieved similar results with a new low-cost low-coherence reflectometry technique, which is related to earlier techniques for optical fibre characterisation
