ABSTRACT:
A light-emitting element includes a light amplification unit and an external resonator. The light amplification unit has a function of amplifying light. The external resonator is connected to the light amplification unit. The external resonator includes a planar light waveguide and a stress application unit. The planar light waveguide is arranged inside the external resonator. The stress application unit applies stress directly or indirectly to at least a partial region of the planar light waveguide.
