| 摘要 |
The fiber-to-fiber coupling device (1) has several optical input fibers (2) whose light exit side fiber end portions (3) are arranged in central axis (4). The optical probe (6) is provided in exit surface (7) of input fibers and end portion of output optical fiber (5). The optical axes (11) are tilted in the direction of the central axis such that the light beams (8) are exited in the end face entry surface (9) of the light incident side end of the output optical fiber through single lens (12) or ellipsoidal mirror (22) formed of glass or copper. |
