Patent ID: 7710574

Claim:
A device in miniature, the device comprising: a substrate; an optical bench on the substrate, the optical bench comprising: one or more actuators; a moving stage driven by at least one of the actuators; a first connector socket with a fixed position relative to the substrate; a second connector socket on the moving stage; a first optical component coupled to the first connector socket, such that the first optical component is fixed relative to the substrate; and a second optical component coupled to the second connector socket, such that the second optical component moves with the moving stage, relative to the substrate; wherein at least one of the actuators comprises a scanning mechanism comprising at least one elongated rib comprising: a top surface; at least one side wall formed at least in part by deep reactive ion etching (DRIE); dopant in the top surface of the rib; and dopant in the side wall of the rib in an amount sufficient to increase conductivity of the rib, relative to a rib without a doped top surface and a doped side wall.
