| 英文摘要 | The present invention discloses an optical fiber capable of providing optical connection to a semiconductor laser diode (LD) as a light emitting element at high optical coupling efficiency. An optical fiber (5) for optical coupling efficiency improvement is coupled, by a fusion joint technique, to an end portion of an optical fiber (2) which is optically connected to a semiconductor LD (3). The optical fiber (5) for optical coupling efficiency improvement has a circular mode field w and the semiconductor LD (3) has an elliptical mode field , wherein the diameter W1 of the fiber (5) is nearly identical to that of the latter field of the semiconductor LD (3) extending in the ellipse's major axis direction.; Further, an end portion of the optical fiber 5 for optical coupling efficiency improvement on the side of the semiconductor LD (3) is formed into an approximately wedge-like shape and its endmost portion is formed into a lens. As a result of such arrangements, the optical coupling efficiency between the semiconductor LD (3) and the optical fiber (5) for optical coupling efficiency improvement is enhanced, and the optical fiber (5) for optical coupling efficiency improvement is connected between the optical fiber (2) and the semiconductor LD (3), whereby the optical coupling efficiency between the optical fiber (1) and the semiconductor LD (3) can be improved, regardless of whatever mode field diameter (w) the optical fiber (2) has. |
