摘要 | PURPOSE:To reduce operating current density while generating uniformly distributed laser beams by forming a resonator in the direction vertical to a p-n junction, shaping a semiconductor region on the side of the resonator and forming a current path. CONSTITUTION:The circular mesas of a p-n junction composed of an n-type GaAlAs clad layer 11 and a p-type GaAs active layer 12 is formed, and reflecting mirrors 20, 21 are shaped. A p-type GaAlAs layer 14 is buried and grown in the peripheries of the reflecting mirrors. One part of the layer 14 is removed, and an n-type GaAlAs layer 17 is formed. Diffusion potential between the layers 11, 12 is set so as to be made smaller than that between the layers 11, 14 in the constitution. When positive polar voltage is applied to an electrode 19 and forward currents are fed, electrons as minority carriers are injected into the layer 12 through an electrode 18 and the layers 17, 11, 12 and each p-n junction, energy is distributed uniformly, and laser beams having a circular cross section are emitted. |
其他摘要 | 目的:通过在垂直于p-n结的方向上形成谐振器,在产生均匀分布的激光束的同时降低工作电流密度,在谐振器侧形成半导体区域并形成电流路径。组成:形成由n型GaAlAs包层11和p型GaAs有源层12组成的p-n结的圆形台面,并且反射镜20,21成形。在反射镜的周围埋入并生长p型GaAlAs层14。去除层14的一部分,并形成n型GaAlAs层17。层11,12之间的扩散电位设定为比构造中的层11,14之间的扩散电位小。当向电极19施加正极性电压并馈送正向电流时,作为少数载流子的电子通过电极18和层17,11,12和每个pn结注入到层12中,能量均匀分布,并且激光发射具有圆形横截面的梁。 |
