Abstract: An integrated circuit device includes a semiconductor substrate with a top surface, a bottom surface opposite the top surface and an intermediate portion positioned between the top and bottom surfaces. The device also includes interior substrate surfaces defined by at least one void extending from the bottom surface to the intermediate portion.

Abstract: An apparatus for a beam steering device includes a rotator constituting a cylindrical body extending along an axis and defining a central passage therethrough. A wedge-shaped prism is secured to the body within the central passage. The prism has a first surface extending perpendicular to the axis and a second surface extending transverse to the axis. A drive member is provided on one of an axial end surface and a radially outer surface of the body for rotating the rotator. An encoder member is provided on the same surface of the body as the drive member for tracking the position of the rotator.

Abstract: A beam steering device includes a housing and a transceiver that emits and receives light beams through at least one opening in the housing. A rotator includes a cylindrical body rotatably mounted within the housing axially between the transceiver and the at least one opening. A wedge-shaped prism is secured within the body and includes a first surface extending perpendicular to the axis and a second surface extending transverse to the axis. An encoder member and a drive member are provided on an outer surface of the body. Sensors are mounted to the housing to sense the encoder member and provide an encoder signal indicative of a rotational position of the prism about the axis. At least one drive element is mounted to the housing and applies force to the drive member to rotate the body and prism about the axis for steering light beams propagating through the prism.
