Abstract

A surface emitting semiconductor laser comprises a semiconductor multilayer reflecting film of a first conductivity type, a quantum well active layer having at least one quantum well structure, a semiconductor multilayer reflecting film of a second conductivity type and a contact layer of the second conductivity type sequentially stacked in a layered manner inside a concavity formed on a surface of a semiconductor substrate. The contact layer of the second conductivity type is formed in a buried manner so that the surface of the contact layer is approximately flush with the surface of the semiconductor substrate. A second electrode is formed on a part of the surface of the contact layer other than a part left for forming a light guiding region thereon.
