Abstract
The refractive index of Pb1−xSnxTe below the fundamental absorption edge is calculated as a function of photon energy and carrier concentration. Use of the band structure of the Kane theory results in a good agreement of theory with experiment. Numerical values of the refractive index for some values of x in the range 0≤x≤0.42 are given and discussed.Keywords
