Photoabsorption of Molecules at Corrugated Thin Metal Films

Abstract

A phenomenological study has been carried out for the photoabsorption of molecules in the vicinity of a corrugated thin metal film. In particular, perturbative results for a grating silver film have been obtained to first order in the corrugation parameter, where the effect of the incident field coupled with the long-range surface plasmon is observed. Based on the different coupling nature between the radiations from the incident plane wave and from the molecular dipole to the substate film, it is proposed that, through control of the various parameters of the film, enhanced selective photoabsorption may be achieved.
