这项拟议的研究涉及一项关于光纤中交叉相位调制(XPM)效应的实验和理论研究,以及这种效应如何被用来影响一个人的行为通过与另一个超短脉冲一起共同传播光脉冲。该项目分为三个部分。第一部分是关于泵浦脉冲与内部通过受激拉曼散射过程产生的斯托克斯脉冲之间的XPM相互作用。第二部分是关于泵浦和在光纤输入端同时发射的信号脉冲之间的XPM相互作用。允许泵浦脉冲和信号脉冲具有不同的载波波长、不同的脉冲宽度以及它们之间的相对时间延迟。第三部分是关于当泵浦脉冲和信号脉冲具有相同的载流子波长,但激发出的光的正交偏振模式时的XPM相互作用。单模光纤。其目的是研究如何利用XPM相互作用来改变信号脉冲的传播特性(例如它的相位、频率、形状,或频谱)通过强烈的泵浦脉冲。该研究对光子交换和高速光通信等领域的工程应用具有一定的参考价值。
英文摘要
The proposed research is related to an experimental and theoretical study of the effects of cross-phase modulation (XPM) in optical fibers and how such effects can be used for influencing the behavior of one optical pulse by copropagating it together with another ultrashort pulse. The project is divided into three parts. The first part is concerned with the XPM interaction between the pump pulse and the Stokes pulse that is generated internally through the process of stimulated Raman scattering. The second part is related to the XPM interaction between the pump and signal pulses launched simultaneously at the fiber input. The pump and signal pulses are allowed to have different carrier wavelengths, different pulse widths, and a relative time delay between them. The third part is related to the XPM interaction when the pump and signal pulses have the same carrier wavelength but excite the orthogonally polarized modes of a single-mode fiber. The objective is to study how the XPM interaction can be used to modify the propagation characteristics of a signal pulse (such as its phase, frequency, shape, or spectrum) through an intense pump pulse. The study is useful for many engineering applications in the fields of photonic switching and high- speed optical communications.
