A surface emitting laser includes a plurality of semiconductor layers including an active layer over a substrate, and emits laser light in a direction perpendicular to the surface of the substrate. The semiconductor layers including the active layer define a resonator that emits laser light having a first wavelength. A wavelength-converting layer is disposed between the substrate and the resonator. The wavelength-converting layer converts the light having the first wavelength into light having a second wavelength that can pass through the substrate.
