It has recently been shown theoretically that soliton-like waves can be guided by optical waveguiding structures containing at least one Kerr- type, self-focusing medium, and that under conditions of high excitation, spatial solitons can be emitted from such a nonlinear structure. This has led to the prediction of new soliton-based single waveguide devices such as optical limiters and all-optical switches, as well as new modes of coupling between isolated waveguides. This proposal concerns a combined program of theory and experiment, with theory leading the way, to establish the feasibility of observing and utilizing spatial-soliton-based nonlinear guided-wave phenomena in integrated optics. The investigators will initially: (a) extend their previous 2-D cw studies to full 3-D simulations; (b) incorporate more realistic material nonlinearities and assess their effects on these phenomena; (c) address the full 4-D spatio-temporal problem which is associated with pulsed inputs; and (d) search for new soliton-based devices for single and multiple waveguides. Based on these calculations and in parallel with them, experiments will be initiated to investigate both spatial and temporal soliton effects in nonlinear waveguiding structures.

最近从理论上表明，类孤子波可以由包含至少一种克尔型自聚焦介质的光波导结构引导，并且在高激发条件下，可以从这种非线性结构发射空间孤子。 这导致了基于孤子的新型单波导器件的预测，例如光限制器和全光开关，以及隔离波导之间的新耦合模式。 该提案涉及理论和实验的结合计划，以理论为主导，建立在集成光学中观察和利用基于空间孤子的非线性导波现象的可行性。 研究人员首先将： (a) 将他们之前的 2-D 连续波研究扩展到完整的 3-D 模拟； (b) 纳入更现实的材料非线性并评估其对这些现象的影响； (c) 解决与脉冲输入相关的完整 4-D 时空问题； (d) 寻找用于单波导和多波导的新的基于孤子的器件。 基于这些计算并与之并行，将启动实验来研究非线性波导结构中的空间和时间孤子效应。
