摘要	PURPOSE:To improve luminance of the focusing light in a junction semiconductor light-emitting element by a method wherein the lights which are derived from at least two pieces of the columnar protrusions of the light-emitting element having the P-N junctions to be extendedly provided in the vertical direction to the flat plate part in the columnar protrusions are focussed on the core of an optical fiber. CONSTITUTION:A junction semiconductor light-emitting element 3 consists of a flat part B, a plurality of columnar protrusions P provided on one surface of that, electrodes E1 provided on side circumferential surfaces of the columnar protrusions P and an electrode E2 provided on a bottom surface of the flat plate part B. Cylindrical P-N junctions PN1 to be extendedly provided in the vertical direction to the flat plate part B respectively exist in the columnar protrusions P. In this case, the element 3 is constituted in such a way that 9 pieces of the columnar protrusions P, for example, in the element 3 are coupled with a core 2 of an optical fiber When the element 3 is constituted in such a way, the light-emitting element 3 substantially emits only in the vertical direction and moreover, can focus a high-luminance light because two pieces or more of the columnar protrusions P are coupled with the core 2 of the optical fiber
其他摘要	用途：通过一种方法改善结半导体发光元件中聚焦光的亮度，其中来自具有PN结的发光元件的至少两个柱状突起的光可以延伸地设置在柱状突起中的平板部分的垂直方向聚焦在光纤的芯上。组成：结半导体发光元件3由平坦部分B，设置在其一个表面上的多个柱状突起P，设置在柱状突起P的侧周表面上的电极E1和设置在底部的电极E2组成。平板部分B的表面。在平行板部分B的垂直方向上延伸设置的圆柱形PN结PN1分别存在于柱状突起P中。在这种情况下，元件3以9件的方式构成。例如，在元件3中的柱状突起P的一部分与光纤1的芯2耦合。当元件3以这种方式构成时，发光元件3基本上仅在垂直方向上发射并且此外，由于两个或更多个柱状突起P与光纤1的芯2耦合，因此可以聚焦高亮度光。
