A semiconductor module of the present disclosure includes: a base body including a groove part of which two inner side surfaces are inclined, the base body including an electrode pad which is provided on at least one inner side surface; and a semiconductor element including a semiconductor substrate including a first surface, a second surface opposite to the first surface, and two side surfaces which are inclined in a diagonal direction to the first surface and are opposite to each other, a semiconductor layer located on the first surface, and an electrode disposed on at least one side surface. The semiconductor element is located in the groove part so that the at least one side surface is disposed along the at least one inner side surface of the base body, and at least one electrode of the semiconductor element is connected to the electrode pad of the base body.

An optical apparatus includes: an optical component opposed to and spaced apart from a light-emitting surface through which laser light is emitted; a case that houses a semiconductor laser element and the optical component and includes an introduction port for introducing gas and an exhaust port for exhausting the gas; and a flow passage section (i.e., a tubular body) including a spray port for spraying the semiconductor laser element with the gas introduced from the introduction port.

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.
