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 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.

摘要： A packaging assembly for a high-speed vertical-cavity surface-emitting laser (VCSEL) mainly applies a lens assembly consisted of several prisms to split a laser beam emitted by a VCSEL element so as to guide a small portion of the laser beam back to a monitor photodiode (MPD) and the rest of the laser beam to travel away along an optical axis. Such a spectacular design of the lens assembly can not only relieve the VCSEL element from a position right under the optical axis, but can also reduce signal loss by shorting a length of a bonding wire for a corresponding pin through disposing the VCSEL element further close to the corresponding pin. Thereupon, a defect of lights reflected from a lens or a translucent plate on a cap can be substantially improved.

摘要： Provided is a light source device, including: a base member; a semiconductor laser disposed on the base member; a lateral wall portion formed so as to surround the semiconductor laser; a light-transmissive lid covering a gap surrounded by the base member and the lateral wall portion; and a connection member that airtightly connects an upper surface of the lateral wall portion and a lower surface of the lid over an entire perimeter of the lateral wall portion. The lateral wall portion has a reflecting surface which is an inside surface connected to an upper surface, the reflecting surface being inclined so that light emitted from the semiconductor laser is reflected toward the lid. A dielectric film is continuously formed on the reflecting surface and the upper surface. A height of the connection member is greater than a height of the dielectric film formed on the upper surface.

摘要： A microfabricated optical apparatus that includes a light source driven by a waveform, wherein the waveform is delivered to the light source by at least one through silicon via. The microfabricated optical apparatus may also include a light-sensitive receiver which generates an electrical signal in response to an optical signal. The electrical signal may be communicated to external devices by at least one additional through silicon via, and the signals routed to the encapsulated devices by metal traces. The vias may couple a ground plane to a metal trace layer at intervals, effectively quashing the ability of the bondline to interfere with the absorbed or radiated signal frequency.

摘要： A semiconductor module is disclosed. The semiconductor module includes a housing that encloses on a bottom thereof a spacer and a wiring substrate that mounts a semiconductor element thereon. The housing includes a feedthrough that secures one end of a transmission substrate. The other end of the transmission substrate faces the wiring substrate and the spacer. The other end of the transmission substrate provides a lower end and an upper end that form an extension protruding toward the wiring substrate. The upper end is set so close to the wiring substrate but the lower end forms a space for receiving a surplus adhesive oozing between the spacer and the wiring substrate.
