Light emitter device based on a photonic crystal with pillar- or wall-shaped semiconductor elements, and methods for the operation and production thereof

Abstract

A light emitter device () comprises a substrate () and a photonic crystal (), which is arranged on the substrate () and comprises pillar- and/or wall-shaped semiconductor elements (), which are arranged periodically standing out from the substrate (), wherein the photonic crystal () forms a resonator, in which the semiconductor elements () are arranged in a first resonator section () with a first period (d), in a second resonator section () with a second period (d) and in a third resonator section () with a third period (d), wherein on the substrate () the second resonator section () and the third resonator section () are arranged on two mutually opposing sides of the first resonator section () and the second period (d) and the third period (d) differ from the first period (d), the first resonator section () forms a light-emitting medium and the third resonator section () forms a coupling-out region, through which a part of the light field in the first resonator section () can be coupled out of the resonator in a light outcoupling direction parallel to a substrate surface () of the substrate (). Methods for operating and producing the light emitter device () are also described.
