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. WHUDs that employ such optical engines and laser projectors are also described.

Claim (Index 1):
A wearable heads-up display (WHUD), comprising:\n a support structure that in use is worn on the head of a user; a laser projector carried by the support structure, the laser projector comprising:\n an optical engine, comprising:\n a base substrate; \n a plurality of laser diodes, each of the plurality of laser diodes bonded directly or indirectly to the base substrate; \n at least one laser diode driver circuit operatively coupled to the plurality of laser diodes to selectively drive current to the plurality of laser diodes; \n a photonic integrated circuit bonded to the base substrate at a position that is spaced apart from the plurality of laser diodes, the photonic integrated circuit comprising a plurality of input facets and at least one output facet, in operation, the photonic integrated circuit receives a plurality of beams of light at the respective plurality of input facets and wavelength multiplexes the plurality of beams of light to provide an aggregated beam of light at the output facet; and \n a waveguide and sealing medium that covers and hermetically or partially hermetically seals the plurality of laser diodes, the waveguide and sealing medium comprising at least one directly written waveguide that couples the plurality of beams of light emitted by the plurality of laser diodes to the input facets of the photonic integrated circuit; and \n \n at least one scan mirror positioned to receive the aggregate beam of light output at the output facet of the photonic integrated circuit, the at least one scan mirror controllably orientable to redirect the aggregate beam of light over a range of angles.
