本课程主要研究半导体中的光学非线性。其目标是实现更强的光学非线性，从而允许在较低的光强下运行。我们将研究缺陷辅助的光学非线性。这位首席研究员之前的工作是利用量子受限激子，开创了新的共振现象，可以显著增强非线性相互作用。了解屏蔽机理的半绝缘多层材料。还将研究其他非平衡非线性光学现象，如光折变效应的猝灭、光学亚稳和混沌。

This program is concerned with the study of optical nonlinearities in semiconductors. The objective is to achieve stronger optical nonlinearities that permit operation at lower light intensities. Defect-assisted optical nonlinearities will be studied. Prior work by this principal investigator employing quantum-confined excitons has pioneered in new resonant phenomena that can lead to significant enhancements of nonlinear interactions. Semi- insulating multilayer materials for understanding the screening mechanisms. Other nonequilibrium nonlinear optical phenomena such as the quenching of the photorefractive effect, optical metastability, and chaos will also be studied.
