Ultrafast nonlinearities in chip-scale photonic crystals

该项目的目标是研究慢光光子晶体中的超快非线性相互作用，基于最近的进展和向芯片级光信号处理的方向发展。在这个项目中，实验观察以及设备纳米制造、理论和数值模拟将被检验。智力的优点由三个相互关联的研究推力组成。在《推力I》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。在推力二号中，程序将把单个电磁波的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。在推力III中，该计划将研究包括光学信号处理在内的四波混频。更广泛的影响是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，用于下一代芯片级光学信号处理和通信模块。教育外展和计划将使少数群体和代表性不足的群体、K-12学生、高中教师、研究生和本科生受益。教育任务包括通过与GK12计划和双重发现中心暑期计划合作，扩大到哈莱姆区和下布朗克斯区服务不足的教育项目，以开发光学纳米科学和技术教学模块。该计划还将与哈莱姆区的高中科学和物理教师合作，开发一个选修课教学模块，包括理论和实验部分，以及？动手？模块，以加强光学物理与纳米科学和技术相交的进展。

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.
