Abstract
An optical-waveguide device mounted on a fixing member having a pair of opposing upright walls and a sub-mount unit including a metallic sub-mount of a rectangular solid shape inserted between the opposing upright walls and a nonmetallic sub-mount of a rectangular solid shape mounted on the metallic sub-mount, and fixed onto a base table. The fixing member and the sub-mount unit as well as the fixing member and the base table are spot-welded together using YAG welding.
Claims11
1-10. (canceled)
An optical module comprising:
- a base table;
- a plurality of optical-waveguide devices mounted on said base table, said plurality of optical-waveguide devices each including an optical waveguide;
- an optical system including an optical lens, said optical system being configured to optically couple said plurality of optical-waveguide devices;
- and
- a support unit configured to support at least one of said plurality of optical-waveguide devices on said base table,
- wherein said support unit includes:
- a fixing member having a base of a substantially rectangular solid shape fixed onto said base table, and a pair of upright walls standing upright on a top surface of said base and extending to oppose each other;
- and
- a sub-mount unit of a substantially rectangular solid shape sandwiched between opposing wall surfaces of said pair of upright walls at opposing side surfaces thereof, the sub-mount unit being supported by said upright walls apart from said base.
A method of manufacturing an optical module comprising:
- preparing a fixing member including a base of a substantially rectangular solid shape and a pair of upright walls standing on a top surface of said base and extending to oppose each other;
- preparing a plurality of optical-waveguide devices each having an optical waveguide;
- mounting at least one of said plurality of optical-waveguide devices on a sub-mount unit of a substantially rectangular solid shape having two opposing surfaces having therebetween an offset distance that is adapted to an offset distance between said pair of upright walls;
- inserting said sub-mount unit mounting thereon said optical-waveguide device while sliding said opposing surfaces on wall surfaces of said two upright walls;
- and
- optically coupling said at least one of said plurality of optical-waveguide devices with another of said plurality of optical-waveguide device via an optical system including an optical lens, and thereafter fixing together said sub-mount unit and said fixing member and fixing together said fixing member and said base table.
