Patent ID: 6970628

Claim:
A method of attaching a bulk element processing an optical beam to a PLC and optically aligning the bulk element with an optical element formed on the PLC, said method comprising the steps of: a. securing the bulk element to a first side of a substrate; b. securing a first side of a flexure element to the first side of the substrate; c. securing a second side of the flexure element to a first side of PLC on which the optical element is formed such that the bulk element and the optical element are in optical alignment to within a first level of tolerance; and d. subsequent to step (c), exerting a force on at least a second side of the substrate to thereby flex the flexure element, said force causing sufficient flexure of the flexure element to optically align the bulk element and optical element to within a second level of tolerance that is more stringent than the first level of tolerance.
