EAGER Collaborative: >100 GHz Optical Clocking using Self-Modulation of Co-Tunneling Light Emitters

这个项目的目标是探索一种新型的超快光发射器。这些光发射器将提供(i)直接调制光发射器的重大进步，以及（ii）创建一个全新的光发射途径，预计将超过以前的设计，同时减轻效率损失。这些设备的应用包括快速时钟，以及光通信和激光雷达等系统。通过俄亥俄州立大学和赖特州立大学之间的合作，大量接触研究，特别是代表性不足的群体，将有助于推进基于rtd的排放者领域，同时提供教育培育的避风港。该团队还将把适当的研究成果集中在战略商业化上。合作团队将探索这种基于共振隧道二极管（RTD）的新型发射器，作为超快速直接调制发射器的来源。据信，由于慢孔是在没有高阻p型掺杂的情况下产生的，并且是在载流子重组和光发射点通过齐纳隧道产生的，因此这些光发射器将绕过许多过去禁止快速直接光发射器的慢机制。该项目的重点是利用PIs自己的混合分析-数值物理模型进行腔体设计，平衡空穴和电子电流，设计和建模热管理和热提取，制造和测试超快速直接调制光源。目的是利用量子共隧道实现超快速直接调制的首次演示。该研究的预期影响包括：1)低成本，超快的光源，以及(2)用于紧凑时钟信号生成的自时钟光发射器。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。

The goal of this project is to explore a new class of ultra-fast optical emitters. Those optical emitters will provide (i) for the significant advancement of direct modulation optical emitters, and (ii) creation of a wholly new optical emission pathway which is expected to exceed previous designs, while mitigating efficiency losses. Applications of such devices include fast clocks, and systems such as optical communication and LIDAR.Through a collaboration between the Ohio State University and the Wright State University, a significant exposure to research, particularly under-represented groups, will help to advance the field of RTD-based emitters while providing for a haven of educational nurturing. The team will also focus appropriate results of this the research output towards strategic commercialization.The collaborative team will explore this new class of resonant-tunneling-diode (RTD)-based emitters as a source of ultra-fast direct modulation emitters. It is believed that, since the slow holes are generated without highly resistive p-type doping and are created by Zener tunneling exactly at the point of carrier recombination and optical emission, these optical emitters will bypass many of the slow mechanisms that have prohibited fast direct optical emitters in the past. A key focus of this project is working on cavity design, balancing of hole and electron currents using the PIs own hybrid combined analytical-numerical physics models, design and modeling of thermal management and heat extraction, fabrication and testing of ultra-fast direct modulation light emitters. The aim is to achieve the first demonstration of ultra-fast direct modulation using quantum co-tunneling. The expected impact of the research includes: 1) Low-cost, ultra-fast optical sources, and (2) self-clocking optical emitters for compact clock signal generation.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
