Abstract:
1. A method of positioning a light source or photodiode with respect to a focusing lens of an optical subassembly, the method comprising: determining a desired position of the light source or photodiode with respect to the focusing lens; determining an amount of spacing between the light source or photodiode and a mounting surface that is required to position the light source or photodiode at the desired position; and positioning the light source or photodiode at the desired position with respect to the focusing lens using a composite adhesive having a plurality of spacing elements intermixed therein, the positioning of the light source or photodiode relating to z-axis positions along a direction of light propagation from the light source or photodiode to the focusing lens which is determined by a width of the spacing elements intermixed therein.
