我们提出了一种强大的迭代技术来求解集成光学中经常遇到的复杂超越色散方程。我们的方法特别适合多层电介质和等离子体波导，形成许多当代纳米光子器件的基础结构。该解决方案算法从真实域无缝移植到复杂域，即在处理泄漏结构或具有材料/金属损失的结构时，不会产生额外的复杂性。与几种现有的数值方法不同，我们的算法对初始猜测的敏感性显着降低，并且允许在袖珍计算器上直接实现。 (C) 2009 美国光学学会
We present a robust iterative technique for solving complex transcendental dispersion equations routinely encountered in integrated optics. Our method especially befits the multilayer dielectric and plasmonic waveguides forming the basis structures for a host of contemporary nanophotonic devices. The solution algorithm ports seamlessly from the real to the complex domain-i.e., no extra complexity results when dealing with leaky structures or those with material/metal loss. Unlike several existing numerical approaches, our algorithm exhibits markedly-reduced sensitivity to the initial guess and allows for straightforward implementation on a pocket calculator.
