ABSTRACT AN OPTICAL DEVICE An optical fibre (1), has an endface (2) which has been coated with a metal oxide coating (5) such that the light guiding core region (4) of the endface (2) is at least partially bounded by the coating (5) whilst being uncoated itself. The core region (4) thus has a different reflectivity to that of the boundary region (3). The fibre may be used in a system for aligning a waveguide with an optical device.
