1. A semiconductor light-emitting element formed of a semiconductor layer, the semiconductor light-emitting element comprising:
- a multilayer reflecting mirror formed on a substrate;
a light-emitting layer formed on the multilayer reflecting mirror;
a resonator that uses the multilayer reflecting mirror as a lower reflecting mirror and that resonates light emitted from the light-emitting layer; and
a phase shift layer that that shifts a phase of a resonance spectrum of the resonator to generate a standing wave having a plurality of principal modes.

Abstract
A semiconductor light-emitting element formed of a semiconductor layer includes a multilayer reflecting mirror, a light-emitting layer, a resonator, and a phase shift layer. The multilayer reflecting mirror is formed on a substrate. The light-emitting layer is formed on the multilayer reflecting mirror. The resonator uses the multilayer reflecting mirror as a lower reflecting mirror and resonates light emitted from the light-emitting layer. The phase shift layer shifts a phase of a resonance spectrum of the resonator to generate a standing wave having plural principal modes.
