Abstract: A method of manufacturing an optical engine includes bonding a plurality of laser diodes directly or indirectly to a base substrate and coupling at least one laser diode driver circuit to the laser diodes. In operation the at least one laser diode driver circuit selectively drives current to the laser diodes. The method further includes bonding a plurality of collimation lenses to the base substrate proximate the plurality of laser diodes and bonding a cap including at least one wall and at least one optical window to the base substrate. The method also includes bonding a grating waveguide combiner proximate the optical window of the cap. In operation, the grating waveguide combiner receives a plurality of beams of light at a respective plurality of input grating couplers and combines the plurality of beams of light to provide a collimated aggregated beam of light at an output grating coupler.

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. Such optical engines may have various advantages over existing designs including, for example, smaller volumes, better manufacturability, faster modulation speed, etc. WHUDs that employ such optical engines and laser projectors are also described.

Abstract: Systems, devices, and methods for tracking eye movement and gaze direction using infrared light are described. The method includes projecting infrared light from at least one pixel in the display screen to the eye of the user, detecting a plurality of reflections of the infrared light from the eye, determining the relative intensity of each of the plurality of the reflections, identifying, from the plurality of reflections, a region of the eye that corresponds to a relatively low intensity reflection, and determining a position of the eye based on the region of the eye that corresponds to the relatively low intensity reflection.

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.
