| 英文摘要 | PURPOSE:To ensure a high-efficiency coupling between a light beam and an optical fiber by a method wherein an Si-made spheric lens is fixed airtight into an aperture provided in the middle of a metal disk and the disk is polished in the direction of its thickness before a cylinder is installed to serve as a cap. CONSTITUTION:The portion 2 of an Si-made spheric lens 1 is given a finishing polish. Next, the lens 1 is fixed airtight in a disk 4 provided with a through-hole at its center, with the lens 1 positioned so that the center of the portion 2 is located on the central axis 3 of the disk 4. A plane of the disk 4, vertical to the central axis 3 of the disk 4 and crossing the central axis of the lens 1, is polished. A process follows wherein a cylinder 7 is secured airtight to the polished disk 4. A cap designed as such realizes a device wherein a light-emitting element may be hermetically sealed and the light generated by the light-emitting element may go into an optical fiber with a high coupling efficiency. |
