Dispersion-engineered membrane reflectors for reconfigurable dual-directional emission membrane lasers on silicon

目的：研究光子晶体腔内可重构双向发射(垂直和面内)薄膜反射器的Fano共振原理和色散工程方法。智力价值：这项研究将有助于理解Fano共振的基本物理特性，并将其应用于具有独特发射特性的新型纳米光子光源以及垂直腔边发射激光器(VCEEL)。利用Fano共振光子晶片独特的模式特性和色散工程能力，Fano共振硅基薄膜反射器之一将被修改和设计，以促进光耦合到面内波导，利用Si-MR区域内相对较大的场集中。广泛影响：Fano共振原理的研究，加上各种光子晶体腔设计，可以影响广泛的主动和被动光子器件应用，如激光器、探测器、调制器、耦合器和光束路由结构，超小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光束操纵和测距系统的广泛应用是非常必要的。在硅上开发经济而可靠的激光器的成功将使传感、光谱、信号处理和计算全部在一个芯片上实现单片集成。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、努力在这项研究中招收代表性不足的学生，以及与国家实验室和行业合作。

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.
