论文摘要
我们通过相关的非铁疾病的光学波导晶格研究高斯梁的传播。在耦合模式理论的框架中，我们演示了如何调整折射率的假想部分，尽管存在无序，但仍需要调整以实现完美的光束传递。值得注意的是，我们的非富米设计可以有效地消除对角和异对决障碍在波导及其耦合中的影响。因此，波导阵列为在离散光子学的背景下实现了非炎症现象的实验提供了理想的平台。
We investigate the propagation of Gaussian beams through optical waveguide lattices characterized by correlated non-Hermitian disorder. In the framework of coupled mode theory, we demonstrate how the imaginary part of the refractive index needs to be adjusted to achieve perfect beam transmission, despite the presence of disorder. Remarkably, the effects of both diagonal and off-diagonal disorder in the waveguides and their couplings can be efficiently eliminated by our non-Hermitian design. Waveguide arrays thus provide an ideal platform for the experimental realization of non-Hermitian phenomena in the context of discrete photonics.
