A surface emitting semiconductor laser includes: a substrate; a first semiconductor multilayer reflector of a first conduction type that is formed on the substrate and is composed of stacked pairs of relatively high refractive index layers and relatively low refractive index layers; a cavity region that is formed on the first semiconductor multilayer reflector and includes an active region; and a second semiconductor multilayer reflector of a second conduction type that is formed on the cavity region and is composed of stacked pairs of relatively high refractive index layers and relatively low refractive index layers. A cavity length of a cavity that includes the cavity region and the active region between the first semiconductor multilayer reflector and the second semiconductor multilayer reflector is greater than an oscillation wavelength.
