Effects of electromagnetic fields on the nonlinear optical properties of asymmetric double quantum well under intense laser field

- The magnitude of the NOR, SHG and THG peak increase with the electric field.
- The magnitude of the NOR, SHG and THG peak increase with the magnetic field.
- The increase of electric field leads to important effects on the optical properties of ADQW.

In this study, the effects of electric and magnetic fields on the optical rectification and second and third harmonic generation in asymmetric double quantum well under the intense non-resonant laser field is theoretically investigated. We calculate the optical rectification and second and third harmonic generation within the compact density-matrix approach. The theoretical findings show that the influence of electric, magnetic, and intense laser fields leads to significant changes in the coefficients of nonlinear optical rectification, second and third harmonic generation.
