In the present paper, investigations of nonlinear optical rectification, absorption coefficient and refractive index in a 1D Ga$_x$Al$_{1-x}$As/GaAs/Ga$_x$Al$_{1-x}$As quantum dots under a finite square well potential using simulation software such as COMSOL Multi-Physics and Matlab have been carried out in the presence of electric field, hydrostatic pressure and temperature. Results show that the resonant peaks of ORC (optical rectification coefficient) exhibit a blue shift under increasing of the electric field, while a red shift trailed by a blue shift is displayed under increasing of hydrostatic pressure and temperature. Similar trends take place for the refractive index as well as for the absorption coefficient under changing of the electric field, temperature and hydrostatic pressure. The attained theoretical results would pave a novel opportunity in designing, optimizing and applications of nonlinear opto-electronic devices by tuning the performance of the quantum dots and controlling some of their specific properties.
Keywords: confined Stark effect, quantum dot, second harmonic generation, third harmonic generation.
