  • Publication number: 20190196201
    Abstract: Systems, devices, and methods of manufacturing optical engines and laser projectors that are well-suited for use in wearable heads-up displays (WHUDs) are described. Generally, the optical engines of the present disclosure integrate a plurality of laser diodes (e.g., 3 laser diodes, 4 laser diodes) within a single, hermetically or partially hermetically sealed, encapsulated package. Photonic integrated circuits having grating or edge couplers thereon may be used to wavelength multiplex beams of light emitted by the plurality of laser diodes into a coaxially superimposed aggregate beam. A waveguide medium having one or more directly written waveguides may couple light from laser diodes to a photonic integrated circuit, and may optionally hermetically or partially hermetically seal the laser diodes, eliminating the need for a separate seal. Such optical engines may have advantages over existing designs including, for example, smaller volumes, better manufacturability, faster modulation speed, etc.

  • Publication number: 20190113747
    Abstract: Systems, devices, and methods for optical waveguides that are well-suited for use in wearable heads-up displays (WHUDs) are described. An optical device comprises an optical waveguide including a volume of optically transparent material, an in-coupler, an out-coupler, a volume of liquid crystal carried by the volume of optically transparent material, and a controller to modulate a refractive index of the volume of liquid crystal. Light is in-coupled into the waveguide and is propagated along a length of the waveguide by total internal. As the light crosses a thickness of the waveguide the light passes through or within the volume of liquid crystal and is refracted according to the modulated refractive index of the volume of liquid crystal. In this way, light signals can be steered to create an image and/or to move an exit pupil of an image. WHUDs that employ such optical waveguides are also described.

  • Publication number: 20190094543
    Abstract: Systems, devices, and methods for optical waveguides that are well-suited for use in wearable heads-up displays (WHUDs) are described. An optical device comprises an optical waveguide including a volume of optically transparent material having a first longitudinal surface positioned opposite a second longitudinal surface across a width of the volume, a liquid crystal in-coupler, a controller to modulate a refractive index of the liquid crystal in-coupler, and an out-coupler. Light is in-coupled into the waveguide on a path that is dependent on the modulated refractive index of the liquid crystal in-coupler and is propagated along a length of the waveguide by total internal reflection between the longitudinal surfaces before being out-coupled by the out-coupler. In this way, light signals can be steered to create an image and/or to move an exit pupil of an image. WHUDs that employ such optical waveguides are also described.
