Waveguide to V-groove arrangement |
摘要 |
An arrangement of an integrated optical waveguide (1) relative to a V-groove (2) for receiving an optical fibre (5) which is to be optically coupled with an end of the waveguide (1) is described. A waveguide (1) is formed in a crystalline optical substrate (3), and a V-groove (2) formed therein beneath an elongate parallel sided window in the substrate with a centre line (2A) of the V-groove (2) aligned with an end (1A) of the waveguide (1). The parallel sides (2B, 2C) of the window at the end of the V-groove (2) aligned with the waveguide (1) terminate out of alignment with each other in a direction along the length of the V-groove whereby the V-groove undercuts a portion (3A) of the optically conducting layer (3) beneath said end of the waveguide (1). The end of the waveguide (1) therefore overhangs the end of the V-groove (2) to enable the end of an optical fibre (5) to be located in close proximity thereto.
