ABSTRACT:
An array of Fresnel microlenses is fabricated directly on the planar output surface of an array of vertical cavity surface-emitting lasers. A compact integrated assembly comprising precisely aligned lasers and lenses is thereby provided for focusing (or collimating) the output beams of the lasers.
