R. Brazis et al., INPLANE PROPAGATING COUPLED PHOTON-PHONON-MAGNETOPLASMONS, THEIR FIELD STRUCTURE AND DISPERSION IN GAAS ALAS SUPERLATTICES/, Acta Physica Polonica. A, 88(4), 1995, pp. 687-690
The dispersion and field structure of in-plane propagating p-polarized
waves in n-GaAs/AlAs superlattice is studied in the frequency range b
elow 10 THz in the presence of the steady magnetic field which is perp
endicular both to the direction of propagation and periodicity. The ex
istence of non-localized photon-phonon-plasmon modes as well as the ma
gnetic-field-controlled mode localization at selected set of interface
s is predicted.
