Abstract: A method of forming a high voltage optical transformer includes forming a via through a transparent carrier wafer, forming a conductive layer within the via, bonding a solid state lighting (SSL) package to a first side of the carrier wafer, and bonding a photovoltaic (PV) wafer to a second side of the carrier wafer opposite to the first side. The photovoltaic wafer may include an active area and a conductive area located outside of the active area that is in electrical contact with the conductive layer. The method further includes forming both an SSL contact with the solid state lighting package and a PV contact with the conductive layer on the same side of the carrier wafer.

Abstract: A device includes a light source to emit light and a light detector to receive the light emitted by the light source. The device may include a high voltage optical transformer and may be configured such that the light detector is laterally spaced away from the light source. In some architectures, the light source and the light detector may be arranged in a common plane. A photonic integrated circuit may be used to couple light emitted from the light source to the light detector.

Abstract: Eyeglass devices may include a frame shaped and sized to be worn by a user at least partially in front of the user's eyes, a varifocal optical element mounted to the frame, and an eye-tracking element mounted to the frame. The varifocal optical element may include a substantially transparent actuator positioned at least partially within an optical aperture of the varifocal optical element and configured to alter a shape of the varifocal optical element upon actuation. The eye-tracking element may be configured to track at least a gaze direction of the user's eyes, and the varifocal optical element may be configured to change, based on information from the eye-tracking element, in at least one optical property including a focal distance. Various other devices, systems, and methods are also disclosed.
