Abstract
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.
