项目摘要

Nontechnical:Silicon photonics is a rapidly growing industry, potentially reaching an annual value of over a billion dollars in the coming decade. In parallel, the complexity of photonic integrated circuits has increased by more than an order of magnitude. The optical response of silicon at wavelengths used for telecommunications, however, is relatively weak. Current optoelectronic technologies therefore rely on integrating other materials with the desired properties. In this context, graphene has emerged as an excellent candidate to realize silicon-compatible optoelectronic devices. Graphene is an atom-thick, two-dimensional material made from carbon. It is nearly 100 times stronger than steel, conducts heat and electricity efficiently, and has unusual optical properties. Recent experimental reports have already approached the predicted performance limits of graphene-based devices. It is not obvious how the device performance can be further enhanced while simultaneously reducing device size. Thus, new paradigms in graphene-based optoelectronic devices are required. This project will develop a new approach for realizing integrated optoelectronic devices. Nanofabrication will be used to integrate graphene into active devices and engineer the effective optical properties with nm scale resolution. These devices will be fully compatible with CMOS technology and promise dramatic reductions in device footprint and losses, while providing fast-speed with low energy consumption. The project brings together a multidisciplinary team of researchers from the United States, Northern Ireland, and the Republic of Ireland through the NSF-US/Ireland R&D Partnership. International cooperation will provide exceptional opportunities for international student exchange and research collaboration as part of this project.Technical:The proposed work aims to develop a new family of graphene-based CMOS-compatible optoelectronics. The two premises behind the proposed approach are that: (i) via nanofabrication, it is possible to spatially engineer the local refractive index of the device at deep sub-wavelength dimensions; and, (ii) by integrating two-dimensional material layers, it is possible to provide active functionality in a reduced area. The operation of these devices relies on the coupling between a number of resonant nano-photonic modes, which does not only make them robust to fabrication errors but also enables broad optical bandwidth in a reduced footprint. Three main research thrusts are identified: (a) development of high-performance ultra-compact graphene electro-optic modulators. (b) Extension of the proposed design concept to other optoelectronic devices beyond modulators (e.g., phase shifters, active couplers, polarizers, and sensors). (c) Monolithically integrate multiple devices on an optical chip and drive with proper CMOS circuitry. The proposed research is highly transformative since it combines two emerging research concepts so to overcome the main limitations of current integrated optoelectronic technologies.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.

非技术性：硅光子学是一个快速发展的行业，未来十年年产值可能超过十亿美元。与此同时，光子集成电路的复杂性增加了一个数量级以上。然而，硅在用于电信的波长下的光学响应相对较弱。因此，当前的光电技术依赖于集成具有所需特性的其他材料。在这种背景下，石墨烯已成为实现硅兼容光电器件的绝佳候选者。石墨烯是一种由碳制成的原子厚的二维材料。它的强度比钢高近 100 倍，能够高效导热和导电，并且具有不寻常的光学特性。最近的实验报告已经接近基于石墨烯的设备的预测性能极限。如何在减小器件尺寸的同时进一步增强器件性能尚不明显。因此，需要基于石墨烯的光电器件的新范例。该项目将开发一种实现集成光电器件的新方法。纳米加工将用于将石墨烯集成到有源器件中，并以纳米级分辨率设计有效的光学特性。这些器件将与 CMOS 技术完全兼容，并有望大幅减少器件占用空间和损耗，同时提供快速和低能耗。该项目通过 NSF-美国/爱尔兰研发合作伙伴关系汇集了来自美国、北爱尔兰和爱尔兰共和国的多学科研究人员团队。作为该项目的一部分，国际合作将为国际学生交流和研究合作提供绝佳的机会。技术：拟议的工作旨在开发基于石墨烯的 CMOS 兼容光电器件的新系列。该方法背后的两个前提是：（i）通过纳米加工，可以在深亚波长维度上空间设计器件的局部折射率； (ii)通过集成二维材料层，可以在较小的面积内提供活性功能。这些器件的运行依赖于多个谐振纳米光子模式之间的耦合，这不仅使它们能够抵抗制造误差，而且还可以在更小的占地面积中实现更宽的光学带宽。确定了三个主要研究方向：（a）开发高性能超紧凑石墨烯电光调制器。 (b) 将所提出的设计概念扩展到调制器之外的其他光电器件（例如移相器、有源耦合器、偏振器和传感器）。 (c) 将多个器件单片集成在一个光学芯片上，并用适当的 CMOS 电路进行驱动。拟议的研究具有高度变革性，因为它结合了两种新兴的研究概念，从而克服了当前集成光电技术的主要局限性。该奖项反映了 NSF 的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准进行评估，被认为值得支持。
