Abstract
Optical alignment apparatus is disclosed that includes a heatsink positioned on a supporting substrate and a laser positioned on the heat sink. The laser defines a light emitting axis substantially parallel to the surface of the supporting substrate. A conductive layer is formed on the surface of the supporting substrate adjacent the heat sink and a dielectric layer is formed on the conductive layer. The conductive layer and the dielectric layer define a selected bondline thickness. An optical block is fixedly mounted on the dielectric layer so as to receive light along an optical axis substantially parallel with the surface of the supporting substrate. The bondline thickness is selected to align the optical axis of the optical block with the optical axis of the light generating component.
