In the vertical cavity surface emitting laser, at least one of the reflectors that form the cavity has a refractive index periodic structure produced by arranging a first medium and a second medium so as to make the refractive index change periodically in in-plane directions of the substrate and the cross sectional area of the first medium in the in-plane directions changes in the direction of the thickness of the first medium. The vertical cavity surface emitting laser has reflectors having a wide reflection band.
