  • Patent number: 12216288
    Abstract: Illuminations systems that separate different colors into laterally displaced beams may be used to direct different color image content into an eyepiece for displaying images in the eye. Such an eyepiece may be used, for example, for an augmented reality head mounted display. Illumination systems may be provided that utilize one or more waveguides to direct light from a light source towards a spatial light modulator. Light from the spatial light modulator may be directed towards an eyepiece. Some aspects of the invention provide for light of different colors to be outcoupled at different angles from the one or more waveguides and directed along different beam paths.

  • Patent number: 12181709
    Abstract: An optoelectronic circuit used with signal light comprises photonic devices disposed on a platform. The photonic devices are configured to condition the signal light and are fabricated with an optical characteristic being electronically tunable. A fabricated performance of the optical characteristic can be varied from a target performance due to a difference (e.g., alteration, change, error, or discrepancy) in the process used to fabricate the device. A ground bus, a power bus, and banks of electronic components are disposed on the platform in electrical communication with the photonic devices. The electronic components in a given bank are selectively configurable to tune the optical characteristic of the associated device so a variance can be diminished between the fabrication and target performances of the device's optical characteristic due to the difference in the fabrication process.
