Abstract
In accordance with an embodiment, a gas sensor includes a substrate having a cavity for providing an optical interaction path; a thermal emitter configured to emit broadband IR radiation; a wavelength selective structure configured to filter the broadband IR radiation emitted by the thermal emitter; and an IR detector configured to provide a detector output signal based on a strength of the filtered IR radiation having traversed the optical interaction path.
