| Radiative intersubband plasmon polaritons in multiple quantum well structures, with arbitrary number of quantum wells, are discussed theoretically. The dispersion relations are derived modeling multiple quantum well structure by uniform uniaxial effective medium and using a full set of the Maxwell equations for macroscopic (local) electromagnetic fields. Numerical calculations are performed for a "GaAs--GaAs/AlGaAs multiple quantum well--air" structure corresponding to a typical total internal reflection geometry. Manifestation of these modes in total internal reflection spectra is also considered. |
