Calculation of Linear and Nonlinear Intersubband Optical Absorption in Electric-field Biased Hyperbolic Quantum Wells
加偏置电场的双曲线量子阱中线性与三阶非线性光学吸收系数的计算(英文)

The analytic forms of the linear and the third-order nonlinear optical intersubband absorption coefficients were obtained for general asymmetric quantum well systems using the density matrix formalism.Based on the model,the linear and the third-order nonlinear intersubband optical absorptions in electric-field biased hyperbolic quantum wells were studied.The numerical results were presented for a typical AlxGa1-xAs/GaAs electric-field biased hyperbolic quantum wells.The results show that the contributors to...
