    摘要: A method and apparatus for passively aligning an optical element on an optical die wherein multiple potential mounting pads are supplied for potential mounting of the optical component. Appropriate tables are generated for 1) the response of the optical detecting component for a given light power level as a function of the mounting position of the optical detecting component, and 2) the asymmetry of the light generating component. Given the two tables an algorithm is prepared for automatically determining the appropriate mounting position to provide desired detection device response characteristics for any given light generating component to be mounted on the die.

    摘要: There is disclosed a method of positioning an optical subassembly for testing includes positioning an optical subassembly within a capture zone on a support surface of a test fixture. At least two probes engage surfaces of respective ones of precisely located fiducials in a surface of the optical subassembly. A third probe contacts a surface of the optical subassembly, which in a preferred embodiment may be another fiducial in the surface of the optical subassembly. Upon engagement of the probes with surfaces of respective fiducials and movement of the probes further into respective fiducials, the optical subassembly is translated into more precise alignment with optics of the test fixture.
