Abstract
An optical resonator system includes a multi-strip waveguide structure having spaced semiconductor strips for guiding an IR radiation, a STP resonance structure (STP=slab tamm-plasmon-polariton), wherein the STP resonance structure includes an alternating arrangement of semiconductor strips and interjacent dielectric strips and includes a metal strip adjacent to the semiconductor strip at a boundary region of the STP resonance structure, wherein the metal strip and the adjacent semiconductor strip are arranged to provide a metal-semiconductor interface, and wherein the semiconductor strips of the multi-strip waveguide structure and the semiconductor strips of the STP resonance structure are arranged perpendicular to each other, and an optical coupling structure having a semiconductor layer, wherein the semiconductor layer is arranged between the multi-strip waveguide structure and the STP resonance structure for optically coupling the IR radiation between the multi-strip waveguide structure and the STP resonance structure.
