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. 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。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	A method of manufacturing an optical engine, the method comprising: bonding a plurality of laser diodes directly or indirectly to a base substrate; and bonding a cap comprising at least one wall and at least one optical window to the base substrate, the at least one wall, the at least one optical window, and at least a portion of the base substrate together delimit an interior volume sized and dimensioned to receive at least the plurality of laser diodes bonded to the base substrate, the bonding of the cap to the base substrate providing 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 laser diodes to exit the interior volume.
