Intersecting optical waveguides are an essential element for integrated optic devices. Previous applications have been limited because of the absence of a rigorous theory for this geometry. Such a theory has already been developed by the P.I. and subsequently predicted several unexpected optical characteristics. Also predictions were confirmed experimentally. Theoretical analysis will be extended to examine new optical waveguide devices based on intersecting waveguides and incorporating the electro-optic and higher order nonlinear effects. Electro-optic devices will include high density switch arrays, tunable wavelength filters, and discrete spectrum analyzers. The analysis will be followed by design and fabrication of these devices in LiNbo3. Theory of intersecting guides to treat the case of an optically nonlinear substrate will also be extended. Incorporation of the intersecting waveguide structure into a medium with (reasonable) third order nonlinearity intended. The guided mode and radiation mode coupling results will be integrated into a single coupled-mode theory. This will permit simultaneously accounting for radiation loss and interwaveguide coupling in the analysis and design of intersecting waveguide devices.

交叉光波导是集成光器件的重要组成部分。由于缺乏严格的几何理论，以前的应用受到限制。这样的理论已经由P.I.发展起来，并随后预测了几个意想不到的光学特性。这些预测也得到了实验的证实。理论分析将扩展到研究基于交叉波导并结合电光和高阶非线性效应的新型光波导器件。电光器件将包括高密度开关阵列、可调谐波长滤波器和离散频谱分析仪。分析之后，将在LiNbo3中设计和制造这些器件。在处理光学非线性基板的情况下，相交导线理论也将得到扩展。将相交波导结构合并到具有（合理的）三阶非线性的介质中。导模和辐射模耦合的结果将被整合到一个单模耦合理论中。这将允许在交叉波导器件的分析和设计中同时考虑辐射损耗和波导间耦合。
