| 摘要 | There is provided an optical fiber to be coupled to a laser diode light source. The optical fiber has a wedge-shaped lens for decreasing the influence of reflection light BR1 and returning reflection light BR2, whereby the laser diode light source can be operated with stability. The wedged and lensed optical fiber according to the present invention is arranged such that the optical fiber is formed to have a wedge-shaped lens at the tip end thereof, a ridge as a rooftop is made to include the center tip end of a core, the ridge is inclined by an inclination angle beta with respect to a plane perpendicular to the optical axis of the optical fiber, and the ridge is formed into a semi-cylindrical surface or a conical surface. |
| 其他摘要 | 提供了一种耦合到激光二极管光源的光纤。光纤具有楔形透镜，用于减小反射光BR1和返回反射光BR2的影响，从而可以稳定地操作激光二极管光源。根据本发明的楔形和透镜光纤被布置成使得光纤形成为在其尖端具有楔形透镜，作为屋顶的脊形成为包括芯的中心尖端，脊相对于垂直于光纤的光轴的平面倾斜倾斜角β，并且脊形成为半圆柱形表面或锥形表面。 |
