从理论上研究了GaAs量子点的三阶非线性光学特性。两个量子限制制度进行了分析，并预测大的光学非线性足够窄的线宽。诱导的（双光子）吸收共振的外观预测能量以上的激子共振的量子点半径，这是电子和空穴玻尔半径之间。
Third-order optical nonlinearities of GaAs quantum dots are investigated theoretically. Two quantum confinement regimes are analyzed, and large optical nonlinearities are predicted for sufficiently narrow linewidths. The appearance of an induced (two-photon) absorption resonance is predicted energetically above the exciton resonance for quantum-dot radii, which are between the electron and hole Bohr radii.
