US Patent 9887515 Optical module, optical apparatus, method for fabricating optical module

An optical module includes a bench part and a cap on the bench part. The bench part includes a bench, an electrode, a semiconductor optical device and a lens. The electrode is disposed on the first and second areas of the bench. The semiconductor optical device is disposed on the electrode in the first area. The cap includes a pad electrode, a conductor, a ceiling, a front wall, a first side wall, a first wing, and a rear wall. The first wing is disposed on the first side wall. The pad electrode is disposed on the first wing, and the conductor is disposed on the cap base and connected to the pad electrode. The electrode is electrically connected to the conductor on the second area. The ceiling extends along a first plane. The front wall has a front outer face extending along a second plane intersecting the first plane.
