Surface polariton generation and fluorescence enhancement using a superlens

Abstract

We present a theoretical study of fluorescence enhancement in the vicinity of a superlens slab, the other side of which is connected to a prism. The fluorescent molecule is regarded as an electric dipole. The dipole excitation rate follows Fermi’s golden rule, while its relaxation process has several pathways that can be analyzed within the range of classical electromagnetic theory. The calculated results are explained by surface modes and reveal a great potential of the proposed configuration in enhancing and detecting fluorescence.
