摘要	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 couplers thereon may be used to wavelength multiplex beams of light emitted by the plurality of laser diodes into a coaxially superimposed aggregate beam. 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.
其他摘要	描述了非常适用于可佩戴抬头显示器（WHUD）的制造光学引擎和激光投影仪的系统，设备和方法。通常，本公开的光学引擎将多个激光二极管（例如，3个激光二极管，4个激光二极管）集成在单个气密或部分气密密封的封装封装内。其上具有光栅耦合器的光子集成电路可用于将由多个激光二极管发射的光束波长复用成同轴叠加的聚合光束。这种光学引擎可以具有优于现有设计的各种优点，包括例如更小的体积，更好的可制造性，更快的调制速度等。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 laser diodes, each of the plurality of laser diodes bonded directly or indirectly to the base substrate; a cap comprising at least one wall that, with the base substrate, defines an interior volume sized and dimensioned to receive at least 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 a 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 respective ones of the plurality of input facets and wavelength multiplexes the plurality of beams of light to provide an aggregated beam of light at the output facet.
