In AlGaAs/GaAs vertical p/n junction laser power converters light is injected into the structure through one of the side surfaces of the crystal. It is being refracted in the Al_xGa_(1−x)As gradient layers to the p-n junction. This work is devoted to the theoretical study of the waveguide properties associated with the profile of the refractive index in these layers. The aluminum distribution cases are considered in which refractive index in the waveguide is linear, exponential, and logarithmic.

用于垂直p / n结GaAs激光功率转换器的AlGaAs梯度波导

在AlGaAs / GaAs垂直p / n结激光功率转换器中，光是通过晶体侧面之一注入结构的。它在作为梯度层的Al _x Ga _（1-x）中折射到pn结。这项工作致力于与这些层中折射率分布相关的波导特性的理论研究。考虑铝分布情况，其中波导中的折射率是线性，指数和对数的。
