Abstract:
A micro-optical-electrical-mechanical laser scanner comprising:a silicon-on-insulator substrate having a silicon substrate layer, a buried oxide layer, and a single crystal silicon device layer; a first device layer portion of the single crystal silicon device layer; a micro-mirror fabricated on the first device layer portion; a second device layer portion of the single crystal silicon device layer; a laser positioned on at least a portion of the silicon-on-insulator substrate to selectively emit laser light at the micro-mirror; a hinge connecting the first device layer portion and the second device layer portion of the single crystal silicon device layer; and a bimorph material layer deposited over at least a portion of the hinge, the bi-morph material layer having a built-in stress wherein the micro-mirror and at least a portion of the hinge are released from the buried oxide layer and the bimorph material causes the hinge to move the released micro-mirror out of a horizontal position.
