Abstract
An optical subassembly may include a plurality of optical semiconductor devices arrayed such that a plurality of light beams respectively traveling in parallel in a first direction are emitted therefrom or incident thereon. The optical subassembly may also include a carrier on which the plurality of optical semiconductor devices are mounted. Adjacent ones of the plurality of optical semiconductor devices may be located at positions shifted in a second direction orthogonal to the first direction and may be shifted in the first direction so as not to face each other in the second direction.
