英文摘要	An optical coupling mount for use in coupling light between a semiconductor waveguide device (2, 42) and an optical fibre comprises a silica based spot size converter (3, 43) located on an optical bench (1, 40) with a trench (8, 47) and grooves (9, 48), whereby the semiconductor device (2, 42) can be positioned in close alignment with the spot size converter (3). The spot size converter (3) comprises a tapered upper waveguide (4, 45) located above a non-tapered lower waveguide (6, 44). The dimensions of the spot size converter (3) are such that a semiconductor device emitting a small, astigmatic optical beam can be efficiently coupled to a single mode fibre requiring a larger, concentric beam.
