• Confined electrons in coupled triangular quantum wires.
• Calculations are in the effective mass and parabolic band approximations.
• Diagonalization method to find the eigenfunctions and eigenvalues.
• Comparative analysis of absorption and refractive index change.
This work concerns theoretical study of confined electrons in a low-dimensional structure consisting of three coupled triangular GaAs/AlxGa1−xAs quantum wires. Calculations have been made in the effective mass and parabolic band approximations. In the calculations a diagonalization method to find the eigenfunctions and eigenvalues of the Hamiltonian was used. A comparative analysis of linear and nonlinear optical absorption coefficients and the relative change in the refractive index was made, which is tied to the intersubband electron transitions.
