摘要	Systems, devices, and methods for optical engines and laser projectors that are well-suited for use in wearable heads-up displays (WHUDs) are described. Generally, the optical engines 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 may be used to combine beams of light emitted by the plurality of laser diodes. 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. WHUDs that employ such optical engines and laser projectors are also described.
其他摘要	描述了非常适用于可佩戴抬头显示器（WHUD）的光学引擎和激光投影仪的系统，设备和方法。通常，光学引擎在单个，气密或部分气密密封的封装封装内集成多个激光二极管（例如，3个激光二极管，4个激光二极管）。具有光栅或边缘耦合器的光子集成电路可用于组合由多个激光二极管发射的光束。具有一个或多个直接写入的波导的波导介质可以将来自激光二极管的光耦合到光子集成电路，并且可以可选地气密地或部分地气密地密封激光二极管，从而不需要单独的密封。还描述了采用这种光学引擎和激光投影仪的WHUD。
主权项	An optical engine, comprising: a base substrate; a plurality of chip submounts bonded to the base substrate; a plurality of laser diodes, each of the plurality of laser diodes bonded to a corresponding one of the plurality of chip submounts; at least one laser diode driver circuit bonded to the base substrate, the 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; and a cap comprising at least one wall and at least one optical window that together define an interior volume sized and dimensioned to receive at least the plurality of chip submounts and the plurality of laser diodes, the cap being bonded to the base substrate to provide a hermetic or partially hermetic seal between the interior volume of the cap and a volume exterior to the cap, and the optical window positioned and oriented to allow light emitted from the plurality of laser diodes to exit the interior volume.
