摘要： A light emitter device (100) comprises a substrate (10) and a photonic crystal (20), which is arranged on the substrate (10) and comprises pillar- and/or wall-shaped semiconductor elements (21), which are arranged periodically standing out from the substrate (10), wherein the photonic crystal (20) forms a resonator, in which the semiconductor elements (21) are arranged in a first resonator section (22) with a first period (d1), in a second resonator section (23) with a second period (d2) and in a third resonator section (24) with a third period (d3), wherein on the substrate (10) the second resonator section (23) and the third resonator section (24) are arranged on two mutually opposing sides of the first resonator section (22) and the second period (d2) and the third period (d3) differ from the first period (d1), the first resonator section (22) forms a light-emitting medium and the third resonator section (24) forms a coupling-out region, through which a part of the light field in the first resonator section (22) can be coupled out of the resonator in a light outcoupling direction parallel to a substrate surface (11) of the substrate (10). Methods for operating and producing the light emitter device (100) are also described.

摘要： The invention relates to a laser device (100) comprising a substrate (10), on the surface of which an optical waveguide (11) is arranged, which has an optical resonator (12, 13) with such a resonator length that at least one resonator mode forms a stationary wave in the resonator (12, 13), and an amplification medium that is arranged on a surface of the optical waveguide (11), wherein the amplification medium comprises a photonic crystal (20) having a plurality of column- and/or wall-shaped semiconductor elements (21) which are arranged periodically on the surface of the optical waveguide (11) while protruding from the optical waveguide (11), and wherein the photonic crystal (20) is designed to optically interact with the at least one resonator mode of the optical resonator (12, 13) and to amplify light having a wavelength of the at least one resonator mode of the optical resonator (12, 13). The invention also relates to methods for the operation and production of the laser device.
