Abstract: An electrically-operable laser device for emitting light at least at a wavelength includes a substrate; at least a first in-plane resonator; a first electrode; a lasing gain medium; and a second electrode. Each resonator includes at least two solid materials having an electrical conductivity below 3 S/m, wherein two or more of the solid materials differ in their refractive indices. The top surface of the first in-plane resonator is planar and has a root mean square roughness below 5 nm. The first resonator is either a) situated above the substrate, or b) comprises a material of the substrate as a first of the at least two solid materials. Any further in-plane resonators, if present, are situated above the substrate.
