| Abstract: | The electron-phonon interaction influences on linear and nonlinearoptical absorption in cylindrical quantum wires (CQW) with aninfinite confining potential are investigated. The opticalabsorption coefficients are obtained by using the compact-density-matrix approach and iterative method, and thenumerical results are presented for GaAs CQW. The results show thatthe electron-phonon interaction makes a distinct influence on opticalabsorption in CQW. The electron-phonon interaction on the wavefunctions of electron dominates the values of absorptioncoefficients and the correction of the electron-phonon effect on theenergies of the electron makes the absorption peaks blue shift andbecome wider. Moreover, the electron-phonon interaction influence onoptical absorption with an infinite confining potential is differentfrom that with a finite confining potential. |
