Study of dipole moment calculations for various transitions on polarization state of output radiation

Bafna, Manish Kumar

Abstract

The electron and hole wave functions have been studied in the present paper using envelope function approximation. The hole Hamiltonian in a hexagonal crystal is obtained from the Luttinger Hamiltonian. The total angular momentum F and parity will be conserved leading to the mixing of states with same F value and equal parity. The values of dipole moments calculated for various transitions are discussed in the present paper. If a given transition is allowed in the dipole approximation with linearly polarized light, it cannot be allowed with circularly polarized light and vice-versa.
