Abstract:
A method of alignment in an optoelectronic assembly (10), the assembly including one or more optoelectronic devices (40, 400) and interfacing means (70) for interfacing from the one or more devices (40, 400) to one or more corresponding optoelectronic components (80, 85) external to the assembly (10), the method characterised in that it includes the steps of:(a) defining one or more regions (65) of the interfacing means (70) to which the one or more devices are responsive to or emissive towards, thereby rendering the one or more regions (65) delineated for processing purposes; (b) processing the assembly (10) to generate one or more alignment features (200, 300) at the one or more regions (65), the one or more features (200, 300) operable to assist with aligning the one or more external components (80, 85) relative to their respective one or more devices (40, 400) within the assembly (10); (c) aligning the one or more components (80, 85) to their respective features (200, 300) so as to be operable to emit towards or receive radiation from their respective one or more devices (40, 400); and (d) applying attaching means (810) for attaching the one or more external components (80, 85) to the assembly when aligned to their respective features (200, 300), the one or more components thereby optically aligned to their corresponding one or more devices (40, 400) within the assembly (10).
