Donor-impurity-related second and third harmonic generation and optical absorption in GaAs-(Ga,Al)As 3D coupled quantum dot-rings under applied electric field

Nonlinear Optical Second Harmonic Generation Characteristics in Cylindrical GaAs/Ga1–ηAlηAs Quantum Dots

“…That influences the energy level structure and optical response properties, enabling precise control over quantum systems and advancing our exploration of nonlinear optical effects with them. [21][22][23][24] Researchers have been deeply interested in this field and carried out a lot of work on it, aiming to achieve precise control and optimization of nonlinear optical effects in constrained quantum structures by adjusting the strength, shape, and spatial distribution of the constraint potential. [25][26][27][28][29][30][31][32] These research efforts have provided theoretical and experimental foundations for the designs and applications of novel optical devices.…”
