Abstract

We model the operation of a micro-optical interferometer for surface plasmon polaritons (SPPs) that comprises an SPP beam-splitter formed by equivalent scatterers lined up and equally spaced. The numerical calculations are carried out by using a vector dipolar model for multiple SPP scattering. The SPP beam-splitter is simulated for different angles of the incident SPP beam, radii of the particles, and inter-particle distances in order to find a suitable configuration for realization of a 3dB SPP beam-splitter. The results obtained are in good agreement with experimental data available in the literature. The feasibility of fabricating an interferometer is thereby corroborated and the calculated intensity maps are found rather similar to those experimentally reported.
