论文摘要
波导阵列为设计电路元件提供了巨大的潜力，该电路元件对于制造能够处理由光编码的信息进行的光学设备所必需。在这项工作中，我们研究了由Kerr型波导阵列组成的一个维光晶格中局部梁的存在和稳定性。我们分析了离散翻译对称性被打破的情况，而其中一个波导缺乏非线性响应。具体而言，我们确定了参数的空间，其中实现了整个晶格的相干和稳健的迁移率。此外，当局部梁直接与杂质相互作用时，我们计算出反射和传输系数，发现它取决于系统参数的可变过滤器。我们的结果将阐明开发解决方案，以在未来的光学设备内传输过程中保持未改变的信息。
Waveguide arrays offer enormous potential to design circuit elements essential to fabricate optical devices capable to processing information codified by light. In this work we study the existence and stability of localized beams in one dimensional photonic lattices composed by a Kerr type waveguide array. We analyzed the case where discrete translation symmetry is broken in as much as one of the waveguides lacks a nonlinear response. Specifically, we determined the space of parameters where a coherent and robust mobility across the lattice is achieved. Moreover, we calculate the reflection and transmission coefficients when localized beams interact directly with the impurity, finding that it behaves as a variable filter depending of system parameters. Our results would shed light on develop solutions to keep unaltered information during its transmission within future optical devices.
