Annotation
In this work, the spectral dependence of the one-photon light absorption coefficient in semiconductors with cubic symmetry is calculated, taking into account the degree of polarization and the contribution of the coherent saturation effect within the framework of the Kane approximation. The optical transitions from the subbands of the valence band to the spin–orbit split-off band are considered. It is shown that the one-photon absorption coefficient for both linearly and circularly polarized light initially increases with frequency, then decreases after passing through a minimum. Such spectral behavior of the one-photon light absorption coefficient is explained by the corresponding behavior of the hole distribution function.
