Abstract
An optical sensing system includes an optical sensor that includes a substrate having an upper surface and a plurality of tapered walls on the substrate, wherein at least one of the tapered walls is aligned along a longitudinal direction, wherein the plurality of tapered walls comprise sloped surfaces oriented at oblique angles relative to the upper surface, wherein the sloped surfaces are configured to adsorb molecules of a chemical sample, a light source configured to emit an incident light beam to impinge the plurality of tapered walls adsorbed with molecules of the chemical sample; and a detector that can collect light scattered by the plurality of tapered walls to allow a determination of the sample chemical.
