Intersubband absorption in modulation-doped V-shaped quantum wires

The calculation of the intersubband absorption in a modulation-doped V-shaped-quantum-wire (V-QWR) is presented. The method is based on self-consistent solving of the single band Schrodinger equation in a nonparabolic approximation. Our calculation shows that the absorption spectrum is anisotropic and has two absorption peaks at 19 meV and 115 meV depending on light polarization.
