Abstract:
1. An optical module optically coupled with an external optical fiber, comprising: a semiconductor optical device to emit signal light, said semiconductor optical device providing an optical axis substantially perpendicular with an optical axis of said external optical fiber; a thermo-electric cooler that mounts said semiconductor optical device thereon to control a temperature of said semiconductor optical device; a lens that concentrates said signal light on said external optical fiber; a mirror that reflects said signal light propagating along said optical axis of said semiconductor optical device toward said external optical fiber; a lens carrier that mounts said lens and said mirror thereon, said lens carrier including a pair of sidewalls, a slope portion and a bottom, said slope portion connecting said side walls and mounting said mirror thereon, said slope portion making an angle of substantially 45° with respect to said bottom, said side walls and said slope portion forming a mounting space where said lens is mounted therein; and a multi-layered ceramic package that installs said semiconductor optical device, said lens carrier with said lens and said mirror, and said thermo-electric cooler, wherein said thermo-electric cooler mounts said lens carrier with said lens thereon.
