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.

A fluid sensor includes a substrate having a top main surface region, wherein the top main surface region of the substrate forms a common system plane of the fluid sensor, a thermal radiation emitter on the top main surface region of the substrate, an optical filter structure on the top main surface region of the substrate, a waveguide on the main top surface region of the substrate, and a thermal radiation detector on the top main surface region of the substrate, wherein the thermal radiation detector provides a detector output signal based on a radiation strength of the filtered thermal radiation received from the waveguide.
