The electron states as well as the nonlinear optical rectification and second and third harmonic generations are investigated in a GaAs‐based V‐groove quantum wire. The single band effective mass Schrödinger equation is solved using the finite element method. The nonlinear optical coefficients were calculated from expressions derived within the compact density matrix method. It is found that this...
The optical absorption response of an elliptical quantum‐dot‐type nanostructure is investigated by numerically determining the electron states within the effective mass and parabolic approximations via the finite element method, taking into account the effect of an externally applied electric field. Validation of the numerical procedure is discussed through the comparison with analytical results...
