Light propagation in multilayer structures: unconventional calculations

We present a numerical scheme for the calculation of light propagation in multilayer structures, including non-standard computations of interest for the photonics community. Computation of light propagation in stratified structures is a well-established field due to the development of thin film technology and research over the past decades. In this context, our group developed a numerical software package for the optical characterization of materials in single layer and multilayer structures using spectral photometric and ellipsometric measurements. We have implemented of a numerical scheme that complements the capacities of the above mentioned software and aims to be a tool for researchers and students in order to understand and simulate phenomena like the attenuated total reflection or the generation of plasmons at metal-dielectric interfaces. These phenomena, which can be fully described from the point of view of classical optics, obtained a renewed interest due to the progress in controlling light-matter interactions at the near field scale. Our approach consists in determining the full electromagnetic field at any given point of an arbitrary multilayer structure, in opposition to standard thin film software, where only the tangential components of the field are taken into account to compute far-field magnitudes. We illustrate our numerical scheme with different simulations and discuss possible future applications
