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.

该项目的目标是探索一类新的超快光发射体。这些光发射器将提供(I)直接调制光发射器的显著进步，以及(Ii)创建一种全新的光发射路径，该路径预计将超过以前的设计，同时减少效率损失。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莱特州立大学之间的合作，大量接触研究，特别是代表不足的群体，将有助于推动基于RTD的排放者领域的发展，同时为教育培养提供避风港。该团队还将把这一研究的适当成果和研究成果集中在战略商业化上。合作小组将探索这种基于共振隧道二极管(RTD)的新型发射器，作为超高速直接调制发射器的来源。人们认为，由于慢空穴是在没有高阻p型掺杂的情况下产生的，并且是由恰好在载流子复合和光发射的点上的齐纳隧道产生的，因此这些光发射器将绕过过去禁止快速直接光发射器的许多慢机制。该项目的重点是腔体设计，使用PI自己的混合分析-数值物理模型平衡空穴和电子电流，热管理和热提取的设计和建模，超高速直接调制光发射器的制造和测试。其目的是实现第一个使用量子共隧道的超快直接调制演示。这项研究的预期影响包括：1)低成本、超高速光源，以及(2)用于紧凑时钟信号产生的自时钟光发射器。该奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。
