Abstract

Simultaneous effects of spin-orbit interaction, external electric and magnetic fields and quantum confinement on the optical absorption coefficient and refractive index of a mono-layer and coaxial quantum wires are investigated in this paper. Finite element method and numerical calculations are established to find energy eigenvalues, energy eigenfunctions and transition dipole moments to obtain desired optical parameters. Results show that spin-orbit interaction exhibits different effects at various field strengths and dimensions. Due to the anti-crossing of energy states and tunneling effect new results are observed in comparison with usual nanostructures.
