Abstract: A vertical comb drive assembly may include a rotor assembly. The rotor assembly may include a comb anchor to attach the rotor assembly to a base, a comb rotor attached to the comb anchor, and a movable element attached to the comb rotor. The vertical comb drive assembly may include a stator assembly. The stator assembly may include a plate anchor to attach the stator assembly to the base, a plate, wherein the plate forms a comb stator, and a plate hinge to connect the plate to the plate anchor. The plate hinge and the plate may be configured for moving the plate from a first position where the comb rotor and the comb stator are both in a first plane to a second position where the comb rotor is in the first plane and the comb stator is in a second plane.

Abstract: A micro-electro-mechanical system (MEMS) device includes a mirror; at least one hinge; an electrostatic comb structure; and a control device. The control device causes, for a period of time, a voltage to be supplied to the electrostatic comb structure to cause the electrostatic comb structure to tilt the mirror about the at least one hinge in a particular direction. The control device causes, after the period of time and at an instant of time, the voltage to cease being supplied to the electrostatic comb structure. A tilt angle of the mirror, at the first instant of time, is less than a maximum tilt angle of the mirror in the particular direction. An angular momentum of the mirror, at the instant of time, is greater than zero kilogram meters squared per second in the particular direction.

Abstract: A micro-electro-mechanical system (MEMS) device may include a mirror structure suspended from a first hinge and a second hinge that are arranged to enable the mirror structure to be tilted about a tilt axis. The mirror structure may include a first actuator and a second actuator located on opposite sides of the tilt axis. The MEMS device may include a fixed electrode coupled to first actuator to cause the mirror structure to tilt about the tilt axis in a first direction based on a fixed voltage applied to the fixed electrode. The MEMS device includes a driving electrode coupled to the second actuator to cause the mirror structure to tilt about the tilt axis in a second direction opposite from the first direction based on a driving voltage applied to the driving electrode.

Abstract: A micro-electro-mechanical system (MEMS) device may comprise a first layer that includes a stator comb actuator; a second layer that includes a rotor comb actuator; a mirror structure that includes a mirror; and a first set of hinges and a second set of hinges configured to tilt the mirror structure about a first axis of the MEMS device based on a driving torque caused by the stator comb actuator engaging with the rotor comb actuator. The first set of hinges may be configured to resist a lateral linear force on the mirror structure in a direction associated with the first axis caused by the stator comb actuator engaging with the rotor comb actuator. The second set of hinges may be configured to resist an in-plane torque on the mirror structure about a second axis of the MEMS device caused by the stator comb actuator engaging with the rotor comb actuator.

Abstract: In some implementations, a liquid crystal on silicon panel includes a backplane with an electrical contact formed on the backplane, a first alignment layer disposed on the backplane and interfacing with the electrical contact, a conductive layer that is light transmissive, a second alignment layer disposed on the conductive layer, and a plurality of beads in an electrically-conductive adhesive between the first alignment layer and the second alignment layer. Electrically-conductive particles within the electrically-conductive adhesive may make the electrically-conductive adhesive electrically-conductive. A first set of the electrically-conductive particles may puncture the first alignment layer to contact the electrical contact, and a second set of the electrically-conductive particles may puncture the second alignment layer to contact the conductive layer. An electrical connection of the electrical contact and the conductive layer may be via a plurality of the electrically-conductive particles.

Abstract: A diffractive MEMS device has an in-plane binary reflective diffraction pattern formed in an outer surface of a tillable platform. The binary reflective diffraction pattern includes rectangular or trapezoidal ridges and valleys, or grooves, of a same depth. The binary reflective diffractive pattern has a high diffraction efficiency even though the surfaces of the “grooves” or “ridges” are not perpendicular to the incoming optical beam. The diffractive pattern is supported by a pair of torsional hinges and is tiltable by an electrostatic actuator. The electrostatic actuator can include at least one side electrode for linearization of dependence of tilt angle on the voltage applied to the actuator.
