Abstract: A high voltage-driven system includes a high voltage optical transformer and a high voltage driven device, where the high voltage optical transformer is located in close proximity to the high voltage driven device. A high voltage connection between the high voltage optical transformer and the high voltage driven device may be shorter than a low voltage connection between the high voltage optical transformer and a low voltage power source used to control the transformer.

Abstract: Beam steering devices include a laser and a metasurface for dynamic beam shaping of laser light. A steering actuator may adjust a metasurface with respect to a laser to dynamically shape the beam. Lasers in a plurality of lasers may be selectively activated to generate a desired beam shape.

Abstract: A high-voltage optical transformer may include (1) an array of light-emitting devices that are connected in parallel with one another and are electrically coupled to an electrical input, (2) a transfer medium, and (3) an array of photovoltaic cells that (A) are optically coupled to the array of light-emitting devices via the transfer medium, (B) are connected in series with one another, and (C) produce an electrical output whose voltage is higher than the electrical input. Various other apparatuses, systems, and methods are also disclosed.

Abstract: A semiconductor light source including a planar optical component that focuses long-wavelength (e.g., infrared) light emitted in a resonant cavity into a nonlinear crystal, which then converts the long-wavelength light into light having a shorter wavelength (e.g., visible light) by frequency doubling. A wavelength-selective reflection layer on the nonlinear crystal reflects the long-wavelength light back into the resonant cavity to form an external cavity and transmits the light having the shorter wavelength out of the external cavity. The resonant cavity includes an active region that emits the long-wavelength light at a high efficiency. The planar optical component includes a micro-lens formed in semiconductor layers or a gradient refractive index lens formed in the nonlinear crystal.

Abstract: An eyebox region is illuminated with first coherent light and second coherent light having a different wavelength than the first coherent light. A first self-mixed interferometer (SMI) signal is generated in response to first feedback light received back from the eyebox region. A second SMI signal is generated in response to second feedback light received back from the eyebox region. Eye data is generated in response to at least the first SMI signal and the second SMI signal.

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: An optical transformer includes a light source and an array of photovoltaic cells optically coupled to the light source, where at least a portion of the photovoltaic cells are connected in series. An optical connector such as a waveguide or an optical fiber may be disposed between an output of the light source and an input of the array of photovoltaic cells. Configured to generate a high voltage output, the optical transformer may be configured to power a device such as an actuator that provides a tunable displacement as a function of voltage.
