我们已经开发出一种激光二极管，其光斑尺寸比为1：2.1，使其有望用于光学打印和记录。图1示出了所开发的激光二极管的示意图。它是通过使用金属有机化学气相沉积，是以前报道的埋条激光器？该结构具有喇叭形条纹，在喇叭形结构的底部具有双注入条纹调制区域。调制器的主电极和辅助电极由形成在p型GaAs接触层和Au电极中的沟道分开。截面A-A'和B-8'在图2中示意性地示出。A-A'截面中的注入电流分布与常规增益引导激光二极管的注入电流分布相同。然而，B-B'截面具有孪生注入
We have developed a laser diode that provides a spot size ratio of 1:2.1, making it promising for optical printing and recording.’ A schematic view of the developed laser diode is shown in Fig. 1. It is fabricated by using metal-organic chemical vapor deposition, as were the previously reported buried stripe lasers? The structure has a flared stripe with a twininjection striped modulation region at the base of the flared structure. The main electrode and the subsidiary electrode for the modulator are separated by channels formed in the p-type GaAs contact layer and in the Au electrodes. Cross-sections A-A’ and B-8’ are shown schematically in Fig. 2. The injection current profile in the A-A‘ crosssection is the same as that of a conventional gain guide laser diode. However, the B-B’ cross-section has a twin injection
