Minibands of magnetoplasmons in semiconductor superlattices in a perpendicular external magnetic field

Scattering of light from metallic films with a corrugated surface: Magnetic field effects in the Voigt geometry

“…We consider P-polarized light incident on the corrugated surface at an angle θ with the normal of the flat surface. We apply the modal Rayleigh-Fano [6] method, the transfer matrix approach and Bloch's theorem [2,4,5,10]. Our results show that it is possible to excite the surface magnetoplasmons in corrugated metallic films like in the free flat surface of metallic films [11,12].…”

“…Different directions of applied fields have been considered for the studies. Three main geometries are known: perpendicular [4], Faraday [5] and Voigt [6]. One motivation to study surface plasmons is the possible technological application of these systems in photonic devices [7,8].…”

Optical response of magnetoplasmons in periodic nanometric structures in the Faraday configuration

“…These systems where the dimensionality is reduced, modify drastically the optical properties of elementary excitations. External magnetic fields provide additional confinement and consequently new features are also manifested in the optical properties of the elementary excitations, such as magnetoplasmons [2] and magnetoexcitons [3].…”

Plasmons at the interface between a corrugated semiconductor film and a binary metallic superlattice

“…Studies have also been performed on the scattering of light from rough surfaces of conductors [2] in the presence of longitudinal plasma waves and semiconductors [3] in the vicinity of excitonic transitions, using nonlocal approaches. Results show field amplitude enhancement as the incident light couples to the surface modes.Investigations of periodic superlattices [4] have found that these systems display energy minibands for the propagation of bulk electromagnetic (EM) waves parallel to the growth direction or minigaps where surface modes exist. The presence of minibands and minigaps in superlattices suggests that such systems can be used as filters.…”
