Objective: This program is to investigate Fano resonance principles and dispersion engineering approaches in photonic crystal cavities, for reconfigurable dual-directional emission (vertical and in-plane) membrane reflector VCSELs on Si. Intellectual Merit: The research will lead to the understanding of the fundamental Fano resonance physical characteristics and applications towards novel nanophotonic light sources with unique emission properties, as well as vertical-cavity edge-emitting lasers (VCEELs). Taking advantage of the unique modal characteristics and dispersion engineering capabilities in Fano resonance photonic crystal slabs, one of the Fano resonance Si-based membrane reflectors will be modified and designed to facilitate light coupling into in-plane waveguides, utilizing relatively large field concentration inside the Si-MR region.Broader Impacts: The investigations of Fano resonance principles, coupled with various photonic crystal cavity designs, can impact a wide range of active and passive photonic device applications, such as lasers, detectors, modulators, couplers, and beam routing structures, etc. The reconfigurable dual-directional emission of ultra-compact lasers is highly desirable for a wide range of applications for both vertically and in-plane integrated photonics, as well as laser beam-steering and ranging systems. The success of the development of economical yet reliable lasers on Si will permit monolithic integration of sensing, spectroscopy, signal processing and computing all on a single chip. The education plan focuses on a few major activities, including interdisciplinary research and education, curriculum development on optoelectronics and green photonics, efforts to recruit underrepresented students in this research, and collaborations with national labs and industry.

目标：该项目旨在研究光子晶体腔中的法诺共振原理和色散工程方法，以实现硅上可重构双向发射（垂直和面内）膜反射器 VCSEL。智力价值：该研究将有助于理解法诺共振的基本物理特性以及对具有独特发射特性的新型纳米光子光源以及垂直腔边缘发射激光器（VCEEL）的应用。利用法诺共振光子晶体板的独特模态特性和色散工程能力，将修改和设计其中一种法诺共振硅基膜反射器，利用 Si-MR 区域内相对较大的场集中，促进光耦合到面内波导中。更广泛的影响：法诺共振原理的研究，与各种光子晶体相结合 腔设计可以影响各种有源和无源光子器件应用，例如激光器、探测器、调制器、耦合器和光束路由结构等。超紧凑型激光器的可重构双向发射对于垂直和面内集成光子学以及激光束转向和测距系统的广泛应用来说是非常理想的。经济而可靠的硅激光器的成功开发将允许将传感、光谱、信号处理和计算全部集成在单个芯片上。该教育计划侧重于几项主要活动，包括跨学科研究和教育、光电子学和绿色光子学课程开发、努力招募参与这项研究的代表性不足的学生，以及与国家实验室和工业界的合作。
