摘要：
A surface emitting laser comprises an underlayer, an active layer formed on the underlayer, a slab layer formed on the active layer and having a photonic crystal structure optically combined with the active layer, and a metal thin film formed on the slab layer and having a periodic fine structure; and enabling taking-out of the light beam propagating in a layer-plane direction in the slab layer through the metal thin film.
