摘要	An optical subassembly (OSA) with a newly arranged optical device is disclosed. The OSA provides a ceramic package that installs a semiconductor optical device, a joint portion welded to a lid of the ceramic package, and an optical coupling portion that receives an external optical fiber. In the OSA, the seal ring put between the top of the multi-layered ceramic package and the lid is isolated from the optical device; accordingly, the lid, the joint portion and the optical coupling portion are electrically isolated from the semiconductor optical device even when the OSA is installed in an optical apparatus such as an optical transceiver.
其他摘要	公开了一种具有新布置的光学装置的光学子组件（OSA）。 OSA提供安装半导体光学器件的陶瓷封装，焊接到陶瓷封装的盖子的接合部分，以及接收外部光纤的光学耦合部分。在OSA中，放置在多层陶瓷封装的顶部和盖子之间的密封环与光学器件隔离;因此，即使当OSA安装在诸如光学收发器的光学设备中时，盖子，接合部分和光学耦合部分也与半导体光学器件电隔离。
主权项	An optical subassembly to be coupled with an external optical fiber, comprising: an optical device providing a ceramic package including a plurality of ceramic layers, a metal lid, and a seal ring put between a top surface of said ceramic layers and said lid, said optical device installing a semiconductor optical device in a space hermetically sealed by said ceramic layers, said metal lid, and said seal ring; a coupling portion that optically couples said external optical fiber with said semiconductor optical device; and a joint portion that assembles said optical device with said coupling portion, said joint portion being welded to said metal lid.
