ALIGNMENT OF AN OPTICAL COMPONENT

摘要

A method of positioning an optical component (1) on an optical by: forming alignment marks (3a-3H) on the chip and positioning the component (1) in alignment with the marks (3a-3H), the alignment marks (3A-3H) comprising mini alignment V-grooves formed in the chip. A photodiode (1) may be aligned with a V-groove (5) in which an optical fibre (6) is located, both types of V-grooves (3A-3H; 5) being formed in the same lithographic step. The photodiode (1) is located over a reflective facet (5A) at the end of the V-groove (5) but does not overlap the end of the fibre (6).
