| 中文摘要 | within the framework of the effective-mass envelope-function theory, the field-dependent intersubband optical properties of a al0.4ga0.6as/al0.2ga0.8as/gaas step quantum well are investigated theoretically based on the periodic boundary condition. a very large stark shift occurs when the lowest subband electron remains confined to the small well while the higher subband electron confined to the big well. the optical nonlinearity in a step well due to resonant intersubband transition (isbt) is analyzed using a density-matrix approach. the second-harmonic generation coefficient chi(2 omega)((2)) and nonlinear optical rectification chi(0)((2)) have also been investigated theoretically. the results show that the isbt in a step well can generate very large second order optical nonlinearities, chi(0)((2)) and chi(2 omega)((2)) can be tuned by the electric field over a wide range. |
