| 英文摘要 | The present invention discloses an optical fibre (20) for coupling to an optical source (18) which includes a core (22) and a tip portion (36). The core (22) is for receiving light directed from the optical source along an optical axis; wherein the core is expanded near one end of the optical fibre, and the expanded core (24) having a diameter larger than other portions of the core that are not expanded. The tip portion (36) is on the end of the optical fibre, wherein the tip portion further includes an endmost face (26), the endmost face being non-perpendicular to the optical axis. A coupling system including such an optical fibre and a method of fabricating a coupling device for the optical fibre are also disclosed. The optical fibre as provided by the present invention not only enables high coupling efficiency with different laser mode sizes, but also reduces the back reflected laser from the optical fibre which may otherwise damage the laser semiconductor chip. |
