摘要:

现代光子学的挑战之一是开发全光学器件,以提高在光学芯片上传输和处理信息的速度和能量效率。最近提出的具有交替增益和损耗区域的宇称时间(PT)对称光子系统被认为可以带来新的功能。在这样的系统中,损耗与增益一样重要,并且根据结构参数,增益补偿损耗。一般来说,PT系统表现出非平凡的非保守波相互作用和相变,这可以用于信号滤波和开关,打开新的前景,光的主动控制。在这篇综述中,我们讨论了广泛的问题,涉及非线性PT对称光子系统的强度依赖的折射率。这种PT对称系统中的非线性为许多效应提供了基础,例如局部模式的形成、非线性诱导的PT对称性破缺和全光开关。非线性PT对称系统可以作为强大的构建模块,用于开发针对主动光控制的新型光子器件。

英文摘要:

One of the challenges of the modern photonics is to develop all-optical devices enabling increased speed and energy efficiency for transmitting and processing information on an optical chip. It is believed that the recently suggested Parity-Time (PT) symmetric photonic systems with alternating regions of gain and loss can bring novel functionalities. In such systems, losses are as important as gain and, depending on the structural parameters, gain compensates losses. Generally, PT systems demonstrate nontrivial non-conservative wave interactions and phase transitions, which can be employed for signal filtering and switching, opening new prospects for active control of light. In this review, we discuss a broad range of problems involving nonlinear PT-symmetric photonic systems with an intensity-dependent refractive index. Nonlinearity in such PT symmetric systems provides a basis for many effects such as the formation of localized modes, nonlinearly-induced PT-symmetry breaking, and all-optical switching. Nonlinear PT-symmetric systems can serve as powerful building blocks for the development of novel photonic devices targeting an active light control.
