Photonic-crystal surface emitting laser and method of manufacturing the same

Abstract

A photonic-crystal surface emitting laser includes an active layer, a photonic crystal layer, and a first semiconductor layer, wherein the photonic crystal layer includes a base material and a plurality of holes periodically disposed in the base material, the plurality of holes extends from one plane of the photonic crystal layer to an opposite plane of the photonic crystal layer, the first semiconductor layer is provided on the one plane of the photonic crystal layer, and a length of each of the plurality of holes in a <110>direction of the photonic crystal layer is smaller than a length of each of the plurality of holes in a <1-10>direction of the photonic crystal layer.
