标题： Arrayed and checkerboard optical waveguides controlled by the electromagnetically-induced transparency

摘要： 我们引入了两种准离散光学系统模型：由四能级N型原子掺杂的波导阵列，以及由三能级{\Lambda }型原子掺杂形成的非线性棋盘图案。 掺杂原子由外部场驱动，以产生电磁感应透明（EIT）效应。 与普通的无源波导系统相比，这些主动系统提供了优势和额外的自由度。 在主动波导阵列中，驱动场可以调整探测信号的线性和非线性传播模式。 非线性棋盘系统支持稳定空间孤子及其“模糊”对应物的传输，无论是直线还是斜线。 显示英文摘要

摘要： We introduce two models of quasi-discrete optical systems: an array of waveguides doped by four-level N-type atoms, and a nonlinear checkerboard pattern, formed by doping with three-level atoms of the {\Lambda}-type. The dopant atoms are driven by external fields, to induce the effect of the electromagnetically-induced transparency (EIT). These active systems offer advantages and addition degrees of freedom, in comparison with ordinary passive waveguiding systems. In the array of active waveguides, the driving field may adjust linear and nonlinear propagation regimes for a probe signal. The nonlinear checkerboard system supports the transmission of stable spatial solitons and their "fuzzy" counterparts, straight or oblique.
