摘要	A w-shaped diffused stripe GaAs/AlGaAs laser and a method for making the same. A double heterostructure layered structure includes a p-type GaAs active layer in contact with a p-type AlGaAs current blocking layer. These layers are sandwiched between two N-type AlGaAs confinement layers. A p-type zinc diffused stripe region having a w-shaped diffusion front extends longitudinally between two reflective surfaces located on respective ends of the device and extends vertically from the surface of the upper confinement layer through a portion of the lower confinement layer and through portions of the various intervening layers. In a method of forming the device, the various layers are formed by epitaxial growth or by metalorganic chemical vapor deposition. The stripe region is formed by diffusing zinc into the device from a source through a pair of parallel slots in a diffusion mask. The zinc diffused into the device is further driven-in by heating the device in the absence of the zinc source.
其他摘要	W形漫射条纹GaAs / AlGaAs激光器及其制造方法。双异质结构层状结构包括与p型AlGaAs电流阻挡层接触的p型GaAs有源层。这些层夹在两个N型AlGaAs限制层之间。具有w形扩散前沿的p型锌扩散条纹区域在位于器件的相应端部上的两个反射表面之间纵向延伸，并从上部限制层的表面垂直延伸穿过下部限制层的一部分并穿过部分各种干预层。在形成器件的方法中，通过外延生长或通过金属有机化学气相沉积形成各种层。通过扩散掩模中的锌从源通过一对平行槽将锌扩散到器件中来形成条纹区域。通过在没有锌源的情况下加热装置，进一步驱入扩散到装置中的锌。
