| 英文摘要 | Optical coupling equipment of the invention for an optical semiconductor and an optical fiber comprises a optical semiconductor, an optical fiber optically coupled to the semiconductor, and a refraction index matching substance filling the space between the semiconductor and the fiber. The refraction index matching substance has a refraction index greater than 1 and smaller than the refraction index of the core of the fiber. The optical distance between the ends of the semiconductor and the fiber with the ends of convex tip changes in association with the refraction index of the refraction index matching substance. In the differences in refraction index between the core of the fiber, as measured on the convex tip, and the outside decreases, the position of the focus of the convex tip changes. Furthermore, if the substances exists outside the active layer, the radiation angle of the laser diode also decreases. As a result, the distance between the facing ends which provides the highest coupling efficiency increases, compared to the equipment lacking the substance. |
