Three-dimensional Magnetooptic Rigorous Coupled Wave Analysis - Application to Nonreciprocal Guiding

Popis výsledku v původním jazyce

In this contribution, we present and discuss two results selected from these problems, with the concentration given to the different special modeling techniques, we have recently developed. First, we have developed a specific numerical technique - magnetooptic 3D MO aperiodic Rigorous coupled-wave analysis (aRCWA), in order to cope successfully with the complexity of wave effects in photonic nonreciprocal (one-way) structures, based on MO effects where unidirectional propagation can appear in the presence of an external magnetic field. We will first report here on a specific extension of the RCWA/aRCWA tool, a fully anisotropic method (including general form of anisotropy of both permittivity and permeability) in three dimensional (3D) case, due to its major application also called magnetooptic RCWA/aRCWA (MORCWA/MOaRCWA). We have then focused on the investigation of the spectral and transmission properties of structures based on InSb/dielectric waveguides at THz frequencies, in particular, on a 3D InSb hybrid Si plasmonic channel guiding structure. Both dispersion diagrams of surface magnetoplasmons, as well as relative spectral transmittances of the forward and backward propagating waves have been provided for this structure, proving the one-way behavior. The method can be easily applied for simulating and designing novel MO (and even fully bi-anisotropic) applications, in more complex novel configurations resembling realistic designs.
