Transfer-matrix method for second-order nonlinear processes with realistic beams

Accurate and fast modeling of electric fields in layered structures have a great scientific and practical value. Prevalent method for that is transfer-matrix method. However, transfer matrix method is limited to infinite plane wave calculations, which can become a limiting factor if a very narrow resonances, e.g. long range surface plasmon polaritons, are present in the structure. In this paper we extend the functionality of standard and nonlinear transfer-matrix method to include beams with arbitrary profile and propose applications for the method.

Dynamical Casimir effect for surface plasmon polaritons

Emission of photon pairs by an interface of asymmetric dielectric and thin metal film excited by a normally falling plane wave is considered. The excitation causes oscillations in time of the phase velocity of surface plasmon polaritons in the interface. This leads to the dynamical Casimir effect - the generation of pairs of surface plasmon polariton quanta, which transfer to photons outside the interface. In case of a properly chosen interface, the yield of two-photon emission may exceed that of usual spontaneous parametric down conversion.
