The light-matter coupling/interaction has been a subject of detailed theoretical description and the basics are all well established. Application of such coupling using metasurfaces towards photo-electronic devices is a promising direction of research and experimentation. Systematic discussion of the relationship between plasmonic and molecular vibrational coupling using metasurfaces is still required. Control of the optical absorption and emission of the functional groups (molecular absorber/emitter) based on geometry and properties of metasurfaces needs experimental verification and validation. This motivated current study to investigate the optical properties of several polymeric materials such as polyimide (PI), widely used in industry, SU-8, which is popular in micro electro-mechanical systems (MEMS) as an side polished Si with the same thickness of polymer were used for the references.
