Abstract:
The linear-circular dichroism of two and three photon absorption of light in semiconductors of cubic symmetry of hole conductivity is theoretically investigated. The matrix elements of two and three-photon optical transitions occurring between the subbands of the semiconductor valence band are calculated. In this case, transitions associated with both non-simultaneous absorption of individual photons and simultaneous absorption of two photons are taken into account, and the spectral and temperature dependences of the coefficient of two and three-photon absorption of polarized radiation are determined.
