The inherent speed and potential for parallel processing make signal manipulation in the optical domain an attractive alternative, but one that requires the ability to produce well-defined nonlinear functions (e.g., wavelength conversion, phase-preserving optical multiplication, logic operations), as well as to direct the optical intermediates and outputs as necessary. We propose to expand our exploration of a new class of photonic devices which possess both of these characteristicst nonlinear photonic crystals (NLPCs). We show theoretically that the structure of an NLPC can be successfully determined for a particular nonlinear optical application - a one-step interchange of optical data between two wavelength division multiplexed (WDM) channels. Preliminary measurements confirm the success of this inversion problem (i.e., desired output 4 NLPC structure). We propose to explore the properties of this and related lattice-based devices and circuits. We also intend to extend this work to quasi-periodic and aperiodic nonlinear optical geometries, and to nonlinear distributions based on nanoscale domain distributions. We believe that this research direction will continue to uncover new and powerful applications of all-optical elements for a wide range of disciplines, including telecommunications, signal processing, and remote sensing.

并行处理的固有速度和潜力使得光域中的信号操纵成为有吸引力的替代方案，但是需要产生良好定义的非线性函数（例如，波长转换、相位保持光学倍增、逻辑运算），以及在必要时引导光学中间体和输出。我们建议扩大我们的探索一类新的光子器件，具有这两个characteristicst非线性光子晶体（NLPC）。我们从理论上表明，一个NLPC的结构可以成功地确定为一个特定的非线性光学应用-两个波分复用（WDM）信道之间的光数据的一步交换。初步测量证实了这种反演问题的成功（即，所需输出4 NLPC结构）。我们建议探索这种和相关的基于晶格的设备和电路的属性。我们还打算将这项工作扩展到准周期和非周期非线性光学几何形状，以及基于纳米尺度域分布的非线性分布。我们相信，这一研究方向将继续为包括电信、信号处理和遥感在内的广泛学科揭示全光学元件的新的强大应用。
