摘要： A semiconductor laser diode structure operable at high power and brightness levels and having a relatively low threshold current, high efficiency, good mode stability, and reduced temperature sensitivity. One disclosed embodiments has twin parallel channels formed in a p type substrate, and employ an n type blocking layer to confine current to a region between and including the channels. The structure includes first and second inactive cladding layers, and an active layer forming a diode junction. The first or lower inactive layer is thinner in the region between the channels, and this results in a higher forward-bias voltage at the center of the active layer, thereby focusing the current near the central position. This current focusing mechanism, which is enhanced by the optional use of a curved active layer, results in the improved characteristics of the structure. By selecting the effective width of a contact stripe overlying the second or upper inactive layer, single or multiple optical gain filaments may be produced. Another disclosed embodiment has no blocking layer, but also employs twin channels to provide a desirable far-field distribution pattern.
摘要翻译：一种半导体激光二极管结构，可在高功率和亮度水平下工作，并具有相对较低的阈值电流，高效率，良好的模式稳定性和降低的温度灵敏度。一个公开的实施例具有形成在p型衬底中的双平行沟道，并且采用n型阻挡层来将电流限制到沟道之间的区域并且包括沟道。该结构包括第一和第二不活动包层以及形成二极管结的有源层。在通道之间的区域中，第一或者更低的非活性层更薄，这导致活性层中心处的正向偏置电压更高，从而将电流聚焦在中心位置附近。这种通过可选地使用弯曲的有源层而增强的当前聚焦机构导致结构的改进特性。通过选择覆盖第二或上部非活性层的接触条的有效宽度，可以制造单个或多个光学增益细丝。另一个公开的实施例不具有阻挡层，但是也使用双通道来提供期望的远场分布模式。

摘要： Various mask configurations and techniques for their employment in a chemical vapor deposition system are disclosed. These masks can be utilized in the fabrication of semiconductor devices. The masks have at least one aperture therein and may be either removed after device processing or formed as an integral part of the semiconductor device being fabricated. In either case, semiconductor devices can be formed with one or more layers characterized by desired spatial variations in their thickness and/ or contour. The integral masking techniques provide for incorporated self alignment which simplifies device processing. The fabrication of semiconductor injection lasers is disclosed as examples of applications of the masking techniques.
