该计划的目的是研究超快非线性相互作用在慢光光子晶体，基于最近的进展和芯片级光信号处理。实验观察，沿着装置纳米结构，理论和数值模拟，将在这个程序中进行检查。智力价值是由三个相互关联的研究重点。在第一阶段中，除了研究超快脉冲的特性外，还将研究慢光光子晶体中的时间孤子和超快脉冲。在推力II中，程序将把单电磁波非线性色散相互作用扩展到两个电磁波之间的非线性耦合。在Thrust III中，该项目将研究四波混频，包括光信号处理，其更广泛的影响是在下一代芯片级光信号处理和通信模块中，用于超短脉冲产生和频率转换的慢光光子晶体中增强的超快非线性。教育推广和方案将有利于少数民族和代表性不足的群体，K-12学生，高中教师，研究生和本科生。教育任务包括通过与GK 12计划和双发现中心夏季计划合作，向哈莱姆和下布朗克斯服务不足的教育计划提供服务，以开发光学纳米科学和技术教学模块。该计划还将与高中科学和物理教师在哈莱姆开发一个选修教学模块，涉及理论和实验部分，和一个？亲自动手模块，以加强在光学物理学与纳米科学和技术的交叉进步。

The objective of this program is to examine the ultrafast nonlinear interactions in slow-light photonic crystals, based on recent advancements and towards chip-scale optical signal processing. Experimental observation, along with device nanofabrication, theory and numerical modeling, will be examined in this program.The intellectual merit is composed of three interrelated Research Thrusts. In Thrust I temporal solitons and ultrafast pulses will be examined in slow-light photonic crystals, in addition to the characterization of the ultrafast pulses. In Thrust II, the program will extend the single electromagnetic wave nonlinear - dispersive interactions to the nonlinear coupling between two electromagnetic waves. In Thrust III, the program will examine four-wave mixing, including optical signal processing.The broader impacts are the enhanced ultrafast nonlinearities in slow-light photonic crystals for ultrashort pulse generation and frequency conversion, in next-generation chip-scale optical signal processing and communication modules. The Educational outreach and programs will benefit minority and underrepresented groups, K-12 students, high-school teachers, graduate and undergraduate students. The educational tasks involve the outreach to under-served education programs in Harlem and Lower Bronx by working with the GK12 programs and the Double Discovery Center summer program, to develop optical nanoscience and technology teaching modules. The program will also work with the high-school science and physics teachers in Harlem to develop an elective teaching module, involving both theoretical and experimental components, and a ?hands-on? module, to reinforce the advances at intersection of optical physics with nanoscience and technology.
