ABSTRACT:
A surface emitting laser which oscillates at a wavelength λ of a blue band, including a photonic crystal layer including a photonic crystal structure, an active layer provided on one surface of the photonic crystal layer, and an electrode provided on the other surface of the photonic crystal layer for injecting electric current into the active layer. The photonic crystal structure has a thickness of 100 nm or more. A laser beam is emitted toward a direction opposite to a side of the photonic crystal layer on which the electrode is provided.
