Abstract
A method of positioning an optical component such as a laser diode (36) in alignment with an optical waveguide (30) comprises forming an elongate V-shaped groove (29) and a depression (31) in a substrate (28). A laser diode (3) is then mounted in the depression (31) and is accurately located therein. An optical fibre (30) is mounted in the groove (29). The relative positions of the depression (31) and the waveguide (30) are such that in use an optical beam may be coupled between the optical component and the waveguide.
