Abstract: Described examples include apparatus having a driving electrode on a substrate. The apparatus has a platform suspended above the driving electrode and conductively coupled to a platform electrode, where the platform is configured to move in a direction perpendicular to a surface of the substrate in response to a voltage difference applied between the driving electrode and the platform electrode. The apparatus also has a mirror post on the platform. The apparatus has a mirror coupled to the platform by the mirror post, where the mirror is rectangular.

Abstract: Described examples include a device includes a first post and a spring supported by the first post. The device also includes a second post coupled to the spring and a mirror on the second post. Additionally, the device includes a movable layer coupled to the spring and to the mirror and a fixed layer, where the movable layer is between the fixed layer and the mirror. The mirror has a width and a length and the length is greater than the width. The mirror is configured to move based on a voltage difference between the movable layer and the fixed layer.

Abstract: A digital micromirror device comprises an array of micromirror pixels, the array comprising a first micromirror pixel and a second micromirror pixel. The first micromirror pixel comprises a hinge, where the hinge is configured to tilt toward a first raised address electrode and toward a second raised address electrode. The first micromirror pixel also comprises a first micromirror coupled to the hinge, where the first micromirror has a sculpted edge. The second micromirror pixel comprises a second micromirror, where a first gap between a first point on the sculpted edge and a nearest point to the first point on the second micromirror is larger than a second gap between a second point on the sculpted edge and a nearest point to the second point on the second micromirror.

Abstract: A microelectromechanical actuator for a light beam steering device is provided that includes memory cells coupled to at least one electronic circuitry component and electrode segments coupled to a respective one of the memory cells via the at least one electronic circuitry component. A flexible metal layer having support pillars is on the electrode segments. Flexible beams are attached to the support pillars and a movable electrode attaches to the flexible beams. A mirror is attached to the movable electrode. When one or more of the electrode segments is activated, the mirror is displaced a distance to steer a light beam output from a light source in a direction.
