    摘要: A novel spatial light modulator system has a high fill factor MEMS array of tilting mirrors used to attenuate wavelength channels in an optical network and an interface control circuit controlling the tilting mirror array via received control signals. The control signals include definitions of the wavelength channels and desired attenuation. This control circuit may or may not be on the same chip as the mirror array. Each mirror is supported by one or more flexures, located symmetrically or asymmetrically with respect to the mirror's center of gravity, providing single-axis or two-axis rotation. Stiffener ribs at mirror edges provide a flatter mirror. Landing electrodes held at the same potential as the mirror prevent stiction, while strain relief slots relieve stress on the mirror or flexures. Mirrors fabricated from polysilicon or metal are polished flat using a CMP technique. This SLM design is non-interferometric, therefore increased angular tilt provides increased attenuation.

    摘要: A multi-axis magnetically actuated device, an array of multi-axis magnetically actuated devices, and a method of fabrication of a multi-axis magnetically actuated device are disclosed. In addition, disclosed is an optical switch comprised of an array of multi-axis magnetically actuated devices and an array of ports adapted to receive an optical waveguide such as, for example, an optical fiber. The multi-axis magnetically actuated device of the invention is capable of rotational movement in two orthogonal directions. In one embodiment, the multi-axis magnetically actuated device comprises two nested rotational members, an inner rotational member nested within an outer rotational member that in turn is nested within a base member. The inner rotational member is mounted by two inner torsional flexures to the outer rotational member that in turn is mounted by two outer torsional flexures to the base member. The inner torsional flexures define an inner axis of rotation while the outer torsional flexures define an outer axis of rotation. The rotational motions of each rotational member arise in response to an interaction between a magnetic influence and a magnetic moment generated by a current passing through coils arranged adjacent to a surface of the inner rotational member. Bulk micromachining techniques enable the members to be formed from a monolithic silicon wafer and can produce a member with a smooth surface. The smooth surface of a member may function as a reflector. In one embodiment, the inner rotational member functions as a reflector.
