英文摘要	A vertical cavity surface emitting laser that includes: a substrate; a first semiconductor multilayer reflector that is a first conductive type and formed on the substrate; an active region formed on the first semiconductor multilayer reflector; a second semiconductor multilayer reflector that is a second conductive type and formed on the active region; a current narrowing layer that is located between the first and second semiconductor multilayer reflectors, and in that a conductive region which has anisotropy in a long side direction and a short side direction within the surface which is parallel to a principal surface of the substrate is formed; and a convex lens member that is formed in a beam window which emits a light on the second multilayer reflector, and that has anisotropy in a long side direction and a short side direction within a surface which is parallel to the principal surface of the substrate.
