Abstract

A method of forming a tapered optical waveguide comprising the steps: a) fabricating a rib waveguide (3) on a first chip (1), b) fabricating a tapering structure (6) on a second chip (2); and c) bonding the first and second chips (1) and (2) together so the tapering structure (6) is optically coupled to the rib waveguide (3) so as to form a tapered waveguide. The rib waveguide (3) and tapering structure (6) can thus be formed independently of each other prior to being bonded together.
