Interband magneto-absorption in narrow-gap semiconductor quantum wells

A theoretical study of optical properties in narrow gap semiconductor quant um wells has been developed using an 8x8 Kane Hamiltonian. The interband tr ansition selection rules have been obtained and a detailed description of t he interband absorption using Voight and Faraday scattering configurations has been given. Interesting effects produced by the intraband admixture, su ch as spin-flip transitions, will be discussed. The complementation of meas urements using different scattering configurations will be analyzed.
