  • Publication number: 20210151498
    Abstract: LED apparatuses featuring etched mesas and techniques for manufacturing LED apparatuses are described, including techniques for reducing surface recombination and techniques for charge carrier confinement. Etched facets of an LED mesa can be passivated using epitaxial regrowth of one or more semiconductor regrowth layers. The one or more semiconductor regrowth layers can include a transition layer. The transition layer can be configured with a bandgap energy between that of layers that are on opposite sides of the transition layer. A transition layer can separate an etched facet and another regrowth layer or separate two regrowth layers. In some instances, selective etching can be performed to preferentially etch a quantum well layer relative to a barrier layer. The selective etching removes surface imperfections, which contribute to surface recombination and which tend to be more prevalent in etched facets of the quantum well layer than etched facets of the barrier layer.

  • Publication number: 20210080724
    Abstract: A display device includes an optical assembly and a display that includes a front surface and a back surface. The display is configured to output image light from the front surface and transmit ambient light from the back surface to the front surface. The optical assembly includes a substrate that has a substantially uniform thickness, a beam splitter, and a reflector. The optical assembly is configured to receive the image light output from the front surface of the display and to transmit a portion of the image light at a first non-zero optical power via an optical path that includes reflections at the reflector and at the beam splitter. The optical assembly is also configured to transmit a portion of the ambient light through the optical assembly at a second optical power without reflection at the reflector. The second optical power is less than the first optical power.

  • Patent number: 10910517
    Abstract: Embodiments of the present disclosure generally relate to light emitting diodes LEDs and methods of manufacturing the LEDs. The LEDs include a mesa-structure that improves light extraction of the LEDs. Furthermore, the process for forming the LEDs refrains from using physical etching to a quantum well active region of the LEDs to prevent compromising performance at the quantum well sidewall.

  • Patent number: 10775616
    Abstract: A lens assembly includes a plurality of micro-LEDs coupled to one or more circuitries affixed to a surface of a lens substrate. At least one micro-LED is positioned within a viewing region of the lens substrate.

An eye tracking unit of the HMD includes the one or more micro-LEDs to project light onto a portion of a user's eye and a detector to collect reflected and/or scattered light from the illuminated portion of the eye. The eye tracking unit tracks the movement of the user's eye. Based on the tracked movement, the HMD adjusts presentation of displayed content such as focus and/or resolutions of the displayed content.

  • Patent number: 10705341
    Abstract: A waveguide display includes a source assembly, an output waveguide, and a controller. The source assembly includes a light source and an optics system. The light source includes source elements arranged in a 1D or 2D array that emit image light that is temporally incoherent and spatially coherent. In some embodiments, the light source includes an array of superluminous LEDs, an array of laser diodes, an array of resonant cavity LEDs, or some combination thereof. The optics system includes a scanning assembly that scans the image light to particular locations based on scanning instructions. The output waveguide receives the scanned image light from the scanning assembly and outputs an expanded image light. The controller generates the scanning instructions and provides the scanning instructions to the light source.

  • Patent number: 10698158
    Abstract: Ion implantation is carried out into a GaN layer of mLEDs to partially or fully convert one or more regions of the crystalline GaN layer to amorphous GaN. As a result, the GaN layer through which light rays propagate have non-uniform refractive indexes that modify propagation paths of some light rays. Ions can be implanted in a region around an active region that emits light to function as an optical waveguide. The ion implanted regions direct light rays that propagate along predetermined directions into predetermined propagation paths thereby to modify the angle of incidence of these light rays. As such, the light extraction efficiency of the mLEDs is increased.

  • Patent number: 10644197
    Abstract: There is herein described a process for providing improved device performance and fabrication techniques for semiconductors. More particularly, the present invention relates to a process for forming features, such as pixels, on GaN semiconductors using a p-GaN modification and annealing process. The process also relates to a plasma and thermal anneal process which results in a p-GaN modified layer where the annealing simultaneously enables the formation of conductive p-GaN and modified p-GaN regions that behave in an n-like manner and block vertical current flow. The process also extends to Resonant-Cavity Light Emitting Diodes (RCLEDs), pixels with a variety of sizes and electrically insulating planar layer for electrical tracks and bond pads.
