The excitation of multiple surface-plasmon-polariton (SPP) waves of different linear polarization states and phase speeds by a surface-relief grating formed by a metal and a rugate filter, both of finite thickness, was studied theoretically, using rigorous coupled-wave-analysis. The incident plane wave can be either p or s polarized. The excitation of SPP waves is indicated by the presence of those peaks in the plots of absorbance vs. the incidence angle that are independent of the thickness of the rugate filter. The absorbance peaks representing the excitation of s-polarized SPP waves are narrower than those representing p-polarized SPP waves. Two incident plane waves propagating in different directions may excite the same SPP wave. A line source could excite several SPP waves simultaneously

“…We have found a deep minimum in the reflectance of the p polarization from absorbing periodically stratified media, remarkable in that it is localized within the stop band of the nonabsorbing stratification. This phenomenon does not seem to have been noticed by workers in the field [1][2][3][4][5].…”

“…We have found a minimum in the reflectance of the p polarization, localized within the stop band. This phenomenon has not been remarked on by workers in the field of reflection by absorbing periodically stratified media [1][2][3][4][5]. Of the two papers that might have seen the effect, [4] is restricted to angles of incidence less than 80°and [5] deals with periodic stacks of graphene layers, where perhaps the absorption is so strong as to drown the effect.…”

Nonabsorbing periodic multilayers reflect both the s(TE) and p(TM) polarizations strongly within the respective stop bands. We find that finite or weakly absorbing layers, for which the reflection is usually strong within the stop bands, can have zero or very weak reflection of the p polarization near the middle of the stop band, close to glancing incidence. Approximate expressions are derived for the location (in angle of incidence and frequency) of the reflection minimum and compared with calculated reflectances for specific multilayers.

Effects of photon reabsorption phenomena in confocal micro-photoluminescence measurements in crystalline silicon J. Appl. Phys. 121, 063101063101 (2017) Giant in-plane anisotropy can be exhibited by a finitely thick periodic multilayer comprising bilayers of an isotropic noncentrosymmetric material and a non-dissipative isotropic medium of negative permittivity, when a dc electric field is applied in the thickness direction. Compared to a homogeneous layer of the noncentrosymmetric material with the same thickness as the periodic multilayer, the latter exhibits an effective in-plane anisotropy that can be three orders larger in magnitude. This enhancement gets more substantial at higher frequencies and is electrically controllable. The incorporation of dissipation reduces the enhancement of the effective in-plane anisotropy, which nevertheless remains significant. We expect the finitely thick periodic multilayer to be useful as a polarization transformer or a modulator in the terahertz regime fully controllable via external dc bias.
