Evaluation of the effective electro-optic constants of free standing multi-quantum-well structures
Résumé
The effective electro-optic constants of an idealized free standing superlattice, composed of thin alternating layers are derived, according to a matrix formulation, as a function of the dielectric and electro-optic constants of each of the constituents. The proposed model is valid only if the energy of light is small compared to the gap of both materials. The results are applied to superlattices with layers of all classes of orthorhombic, hexagonal, tetragonal and cubic symmetries.
