Abstract: A light source or projector for a near-eye display includes a light source subassembly optically coupled to a waveguide concentrator. The light source subassembly may include several semiconductor chips each hosting an array of emitters such s superluminescent light-emitting diodes. The semiconductor chips may be disposed side-by-side, with their emitting sides or facets coupled to the waveguide concentrator, which provides a tight array of output light ports on a common output plane of the concentrator. The output diverging beams at the array of output light ports are coupled to a collimator, which collimates the beams and couples them to an angular scanner for scanning the collimated light beams together across the field of view of the display.

Abstract: An optical dimming device is provided. The optical dimming device includes a photochromic element including a photochromic composition. The photochromic composition includes a combination of a first photochromic material and a second photochromic material having different steady-state absorption profiles. In a direction from a first portion to a second portion of the photochromic element, a concentration of the first photochromic material in the combination decreases and a concentration of the second photochromic material in the combination increases.

Abstract: A device includes an optical assembly and a digital projector. The optical assembly is configured to receive visible scene light at a backside of the optical assembly and to direct the visible scene light on an optical path toward an eyeward side. The optical assembly includes a dimming layer disposed on the optical path. The dimming layer includes a photochromic material that is configured to darken in response to exposure to a range of light wavelengths. The digital projector is disposed on the eyeward side of the optical assembly and is configured to selectively emit an activation light within the range of light wavelengths to activate a darkening of a region of the dimming layer to dim the visible scene light within the region.

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: For small, high-resolution, light-emitting diode (LED) displays, such as for a near-eye display in an artificial-reality headset, LEDs are spaced closely together. A backplane can be used to drive an array of LEDs in an LED display. A plurality of interconnects electrically couple the backplane with the array of LEDs. The backplane can have a different coefficient of thermal expansion (CTE) than the array of LEDs. During bonding of the backplane to the array of LEDs, CTE mismatch can cause misalignment of bonding sites. The higher the bonding temperature, the greater the misalignment of bonding sites. Lower temperature bonding, using materials with lower melting or bonding temperatures, can be used to mitigate misalignment during bonding so that interconnects can be more closely spaced, which can allow LEDs to be more closely spaced, to enable a higher-resolution display.

Abstract: Disclosed herein are techniques for eye illumination for eye position tracking. An illuminator for eye tracking includes a substrate configured to be placed in front of an eye of a user and a light source positioned on a surface of the substrate. The light source is configured to be positioned within a field of view of the eye of the user. A maximum dimension of the light source in a plane parallel to an emission surface of the light source is less than 500 μm.

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.
