New materials and structures, especially those implemented with modern nanotechnologies, along with an original use of various physical effects and along with clever structural/material device designs are the crucial aspects that have to be attacked successfully for photonic devices to become even more efficient, inexpensive, and more desirable in many applications. This proposal aims at contributing to such a challenging goal. The objective of this research is to investigate theoretically and model numerically optical and optoelectronic functionalities based on novel applications of physical effects in material structuralities. Material physical effects such as third-order optical nonlinearities, stimulated emission in semiconductors, interaction of optical waves with electron plasma in metals and semiconductors, and dispersive phenomena in periodic structures will be the main focus of the studies. Nanotechnology structuralities will be considered as a means to implement such novel functionalities. Examples are Kerr-based ultrafast digital switching, plasmon-resonance optical-loss compensating, reconfigurable nonlinear periodic-structure adaptive filtering, or electrical-signal optical storage. The long term objective is to develop powerful and robust simulation/design tools for novel photonic functionalitites implemented in devices for various applications in the fields of communications, signal processing, computing, sensing, and others. Our original theoretical and numerical approaches, such as a new form of a solution to Maxwell's equations and a robust use of linear prolate functions and their eigenvalues, will be the driving methodologies behind our research work towards this objective. Achieving objectives of this proposal can deliver a significant impact on the general area of photonic devices, thus contributing to enabling the materialization of photonics' nature of being ever more pervasive into all fields of our everyday life.

新的材料和结构，特别是那些与现代纳米技术实现，沿着与各种物理效应的原始使用和沿着与聪明的结构/材料器件设计是关键方面，必须成功地攻击光子器件变得更有效，更便宜，在许多应用中更可取。本提案旨在促进实现这一具有挑战性的目标。本研究的目的是研究理论和模型数值光学和光电功能的基础上新的应用物理效应的材料结构。材料物理效应，如三阶光学非线性，半导体中的受激发射，光波与金属和半导体中的电子等离子体的相互作用，以及周期结构中的色散现象将是研究的主要焦点。纳米技术结构将被视为实现这种新功能的一种手段。例如基于克尔的超快数字开关、等离子体共振光损耗补偿、可重构非线性自适应滤波或电信号光存储。长期目标是为通信，信号处理，计算，传感等领域的各种应用的设备中实现的新型光子functionalitites开发强大而强大的仿真/设计工具。我们原来的理论和数值方法，如一个新的形式的解决方案，麦克斯韦方程组和一个强大的使用线性扁长函数及其本征值，将是我们的研究工作背后的驱动方法朝着这一目标。实现该提案的目标可以对光子器件的一般领域产生重大影响，从而有助于实现光子学的本质，使其更加普遍地渗透到我们日常生活的各个领域。
