| 摘要 |
An optical semiconductor module comprises an optical semiconductor element, an optical fiber, a monocrystalline substrate, an airtight sealing member and a reinforcing plate. Light is transmitted through the optical semiconductor element and the optical fiber. The optical semiconductor element and the optical fiber are mounted on the monocrystalline substrate. The optical semiconductor element is sealed airtight by the airtight sealing member. An optical axis aligning mechanism for aligning the optical axis of the optical semiconductor element with the optical axis of the optical fiber is arranged on the monocrystalline substrate. The reinforcing body is welded with metal on the rear surface of the monocrystalline substrate.
