摘要	PURPOSE:To make it possible to easily perform the coupling of the title element with an optical fiber and to contrive to improve a coupling efficiency in such a way as to be able to lead sufficiently photo output in the optical fiber by a method wherein the element is provided with a groove, which leads the optical fiber at the time of coupling of the optical fiber and makes its core layer position on the same optical axis as that of a luminous region. CONSTITUTION:Electrodes 3a and 3b are formed on parts only of a high-luminance end face light emission type LED 1 and a V-shaped mesa groove 8 is valid on the other part. Here, as the outer diameter of an optical fiber strand 2 is phi=125mum, the distance between the deepest part of the groove 8 and an active layer 4 exposed on the upper part of the groove 8 and the angular aperture of the groove 8 are respectively assumed to be (x) and (theta) and the groove 8 is formed so that a formula of 125=2Xsintheta is valid. The optical fiber strand 2 is led by the sidewall by just fitting in from the upper direction and an alignment of a luminous region 7 in the center of the active layer 4 and a core layer 6 of the strand 2 is automatically performed. After this, by fixing with a resin 9, the coupling of an element with the optical fiber strand is completed.
其他摘要	目的：使得可以容易地执行标题元件与光纤的耦合，并且设法提高耦合效率，使得能够通过其中元件的方法在光纤中引导足够的光输出。具有凹槽，该凹槽在光纤耦合时引导光纤，并使其芯层位于与发光区域相同的光轴上。组成：电极3a和3b仅形成在高亮度端面发光型LED 1的部件上，而V形台面凹槽8在另一部分上有效。这里，由于光纤束2的外径为phi =125μm，因此槽8的最深部分与暴露在槽8的上部的有源层4和槽8的角孔之间的距离为分别假设为（x）和θ，并且形成凹槽8使得公式125 = 2Xsintheta是有效的。通过从上方恰好装配，光纤线束2由侧壁引导，并且自动执行有源层4的中心的发光区域7和线束2的芯层6的对准。此后，通过用树脂9固定，完成元件与光纤束的连接。
