从理论上分析了作为垂直腔面发射半导体激光器反馈面的异质多层结构对光腔中激光传输振荡过程的影响．指出其相位匹配和等效反射面位置对改善激光器性能的重要作用．说明目前这种被认为很有希望的微腔结构，实际上难以观察到微腔效应的物理根源，并指出其改进的途径． The effect of heterogeneous multilayer structure as the feedback surface of vertical cavity surface emitting semiconductor laser on laser transmission oscillation in optical cavity is theoretically analyzed. It is pointed out that the phase matching and the position of the equivalent reflecting surface play an important role in improving the laser performance. It shows that the current micro-cavity structure, which is considered promising, can hardly be observed the physical origin of micro-cavity effect and points out the improved approach.
