摘要	PURPOSE:To eliminate the disorder of a far-field pattern and to realize a high coupling efficiency to a fiber by installing a window region provided with a guide layer having a shape which does not spread light radiated to the window region from a region including an active layer to a direction perpendicular to a semiconductor substrate of a semiconductor active optical element and which spreads it only in the horizontal direction. CONSTITUTION:A guide layer 5 which is optically coupled to a light-emitting region 8 having an active layer 3 and which is extended to the advance direction of light is provided. Light in a window region 9 at this time is propagated to the guide layer 5 in a concentrated manner. The thickness and the refractive index of the guide layer 5 are set in such a way that the leak of light especially in the vertical direction is not extended to the surface 12 of the window region; the guide layer 5 has an extended structure as compared with the active layer 3 in such a way that light is not spread two-dimensionally in the horizontal direction. As a result, the amount of reflected light returning to the active layer 3 in the window region 9 is reduced sharply. It is possible to realize a structure whose reflection is low and in which the far-field pattern of radiated light is not disordered.
其他摘要	目的：通过安装一个窗口区域来消除远场图案的混乱并实现对光纤的高耦合效率，该窗口区域设置有引导层，该引导层具有不会从包括以下区域的区域辐射到窗口区域的光扩散的形状。有源层在垂直于半导体有源光学元件的半导体衬底的方向上并且仅在水平方向上扩展它。组成：提供一个引导层5，它与一个发光区域8光学耦合，发光区域8具有一个有源层3，并延伸到光的前进方向。此时窗口区域9中的光以集中的方式传播到引导层5。引导层5的厚度和折射率设定为使得特别是在垂直方向上的光泄漏不延伸到窗口区域的表面12;与有源层3相比，引导层5具有延伸结构，使得光不会在水平方向上二维地扩散。结果，返回到窗口区域9中的有源层3的反射光量急剧减少。可以实现反射低且辐射光的远场图案不混乱的结构。
