Abstract
A light emitting element includes a stacked structurein which a first compound semiconductor layer, an active layerand a second compound semiconductor layermade of GaN-based compound semiconductors are stacked, a mode loss acting portionprovided on the second compound semiconductor layerand configuring a mode loss acting regionthat acts upon increase or decrease of oscillation mode loss, a second electrode, a second light reflection layer, a first light reflection layer, and a first electrode. A current injection region, a current non-injection inner side regionthat surrounds the current injection regionand a current non-injection outer side regionthat surrounds the current non-injection inner side regionare formed on the stacked structure, and a projection image of the mode loss acting regionand a projection image of the current non-injection outer side regionoverlap with each other.
