Abstract

n this paper, it has been shown that the doped disk-like quantum dot with Gaussian impurity can operate as an optical rectifier. The simultaneous presence of impurity and the external electric field in the quantum dot causes to an asymmetric structure. The asymmetric quantum dot can exhibit the significant nonlinear optical properties such as optical rectification. Also, it has been shown that the value of the optical rectification can be controlled by the external field and the Gaussian impurity parameters (strength, decay length and impurity position in the quantum dot). The results of the numerical calculations represent that the optical rectification value of doped quantum dot with the repulsive impurity is stronger than the attractive impurity. Furthermore, the study of the effect of strength and direction of the applied electric field on the optical rectification shows that enhancement of the electric field strength causes to more confinement. Therefore, the optical rectification value decreases, when the value of electric field increases.
