摘要	A vertical cavity surface emitting laser that includes: a substrate; a first reflector of a first conductive type formed on the substrate; an active region formed on the first reflector; a second reflector of a second conductive type formed on the active region; and a current confining layer formed between the first reflector and the second reflector; and a metallic electrode that is formed on the second reflector, and is electrically connected to the second reflector. A conductive region with an anisotropy where a length in a longitudinal direction is different from a length in a short direction is formed in the current confining layer, and an opening defining a beam aperture is formed in the metallic electrode, and a diameter of the opening in the longitudinal direction is smaller than the length of the conductive region in the longitudinal direction.
其他摘要	一种垂直腔表面发射激光器，包括：基板;形成在基板上的第一导电类型的第一反射器;形成在第一反射器上的有源区;形成在有源区上的第二导电类型的第二反射器;以及在第一反射器和第二反射器之间形成的电流限制层;金属电极形成在第二反射器上，并与第二反射器电连接。在电流限制层中形成具有各向异性的导电区域，其中纵向长度不同于短边方向上的长度，并且在金属电极中形成限定光束孔的开口，并且开口的直径在纵向方向上的长度小于导电区域在纵向方向上的长度。
