Abstract AITranslate

General analytic expressions for the absorption coefficient (ACF) of a strong electromagnetic wave (SEM) caused by confined electrons in cylindrical quantum wires (CQW) are obtained by using the quantum kinetic equation for electrons in the case of electron–optical phonon scattering. Second-order multiphoton process is included into the result. The dependence of ACF on the amplitude E 0 and the energy ℏ Ω of a SEM, the temperature T of the system, and radius R of CQW for a specific CQW GaAs/AlAs is achieved due to numerical method. The computational results show that the dependence of ACF on ℏ Ω and R can be applied to optically detect the electric subbands in a CQW.
