Abstract
A gas sensor comprising: a substrate; a grating array disposed on top of the substrate and comprising grates; and voids defined by the grates and configured to confine gas molecules for absorption of light and analysis. A method of gas sensing comprising: generating first light; converting the first light into second light using grates of a grating array; resonating the second light within the grating array; confining gas molecules in voids defined by the grates; and causing the gas molecules to absorb the second light within the voids.
