- 分享到:
摘要：
光学怪波,类比于海洋中的怪波,即具有极高振幅的光学波.非线性薛定谔方程可以作为一种简单的模型来研究光学怪波.多分量耦合的非线性薛定谔方程可研究不同偏振分量的矢量怪波.提出在冷原子体系利用电磁诱导透明(Electromagnetically Induced Transparency,EIT)实现矢量光学亮-亮怪波、暗-暗怪波和亮-暗怪波,并利用调制不稳定性研究产生光学怪波的产生机制.研究结果有助于深刻理解非线性系统的不稳定性本质和动力学性质,并且在光学信息处理和传输中具有潜在的应用价值.
Optical rogue waves,like strong wave packets that appear in oceans,are giant ones corresponding to large-amplitude.Nonlinear Schrodinger equation is used as a simple model to study optical rogue wave.The multi-component coupled nonlinear Schrodinger equation can be used to study vector rogue waves with different polarization components.We propose to use electromagnetically induced transparency(EIT)to realize vector optical bright-bright rogue waves,dark-dark rogue waves and bright-dark rogue waves in cold atomic system,and to study the mechanism of optical strange rogue by using modulation instability.It will help us to have a better understanding of the nature of instability and dynamics of nonlinear systems.The results obtained may have potential applications in optical information processing and transmission.
