摘要	The present invention relates to a quadrangular-pyramid-shaped lensed fiber. One end of the fiber is ground to become quadrangular-pyramid-shaped. Small volume of the tip of the quadrangular-pyramid-shaped fiber is heated to form a semi-ellipsoidal microlens, thereby forming the quadrangular-pyramid-shaped lensed fiber. The advantage of the present invention is that the shape of the semi-ellipsoidal microlens can be controlled by adjusting the angles of the quadrangular-pyramid-shaped fiber according to the aspect ratio of the diode laser so as to enhance the coupling efficiency between an optical fiber and a diode laser.
其他摘要	本发明涉及一种四棱锥形透镜光纤。将纤维的一端研磨成四角锥形。将四角锥形光纤的尖端的小体积加热以形成半椭圆形微透镜，从而形成四角锥形透镜光纤。本发明的优点是可以通过根据二极管激光器的纵横比调整四角锥形光纤的角度来控制半椭圆形微透镜的形状，从而提高光学元件之间的耦合效率。光纤和二极管激光器。
主权项	A quadrangular-pyramid-shaped fiber comprising: an optical fiber having a central axis and an end; and a tapered region at the end of the optical fiber, the tapered region having four slants, four edges and an apex, each two adjacent slants intersecting to form the edges, the four edges intersecting to form the apex, the apex being on the central axis, and two separate edges of the four edges and the central axis being on the same plane.
