Integrated circuits are responsible for most of modern technology today. While electronic circuits have been sufficient for advancing technology until this point, the challenging computational, energy-efficiency, and communication demands of the 21st century require a radically new paradigm. This can be found in silicon photonics, an emerging technology which allows the manipulation of light by integrating optical devices on the same chips as electrical circuits. The ability to control light on a chip has already led to important technological advancements, including ultra-high-speed wired and wireless communications, lens-free imaging, Light Detection and Ranging (LiDAR), gyroscopes without moving parts, gas sensors, and label-free biosensors. This project seeks to solve device simulation and design difficulties which currently severely limit the potential of silicon photonics, ushering in a new generation of chips with unprecedented levels of performance and design complexity, and paving the way for on-chip optical computation and ultra-fast, efficient communication. Leveraging mathematical and computational modeling, this research will engage and train graduate and undergraduate students in multi-disciplinary fields spanning from mathematics to computer engineering and applied physics. Another objective is to engage high school students from local schools interested in STEM, with a specific focus on women and underrepresented groups. This project will spur the growth of powerful new design tools for silicon photonics which will allow human designers to maximize their efforts designing at the system level, rather than at the device level, allowing them to develop highly intricate systems.Due to their large size, small features, and complexity, photonic devices are very challenging to numerically simulate, and the lack of analytical or even approximate solutions further complicates the design of new devices. Advanced numerical techniques based on boundary integral equation methods will be developed in this project and applied to model photonic devices. Unlike present approaches which necessitate volumetric meshing of devices to be simulated, the project's approach only requires meshing the surfaces or boundaries of devices, leading to a significant reduction of problem size and dramatic increases in speed and CPU and memory efficiency. High-order polynomial functions will be used to approximate the electromagnetic unknowns, leading to an almost exponential rate of convergence to the exact solution with respect to the mesh size, in contrast to present methods which can only achieve linear or quadratic convergence. An optimization framework will be designed and implemented which will be capable of automatically designing new, ready-to-fabricate photonic devices without any human intervention other than specification of desired functionality and performance. The efficacy of the new simulation and optimization platform will then be demonstrated by utilizing the framework to design and evaluate real silicon photonic devices such as wavelength demultiplexers, power splitters, and grating couplers.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.

集成电路是当今大多数现代技术的基础。虽然到目前为止，电子电路已经足以推动技术的发展，但21世纪具有挑战性的计算、能源效率和通信需求需要一个全新的范例。这可以在硅光子学中找到，硅光子学是一种新兴技术，它通过将光学器件集成到与电路相同的芯片上来操纵光。在芯片上控制光的能力已经导致了重要的技术进步，包括超高速有线和无线通信、无透镜成像、光探测和测距（激光雷达）、无运动部件的陀螺仪、气体传感器和无标签生物传感器。该项目旨在解决目前严重限制硅光子学潜力的器件模拟和设计难题，引领具有前所未有的性能和设计复杂性水平的新一代芯片，并为片上光学计算和超快速高效通信铺平道路。利用数学和计算建模，这项研究将吸引和培养研究生和本科生在从数学到计算机工程和应用物理的多学科领域。另一个目标是吸引对STEM感兴趣的当地高中学生，特别关注女性和代表性不足的群体。该项目将促进硅光子学强大的新设计工具的发展，这将使人类设计师能够最大限度地在系统级设计他们的努力，而不是在设备级，允许他们开发高度复杂的系统。由于光子器件体积大、体积小、结构复杂，其数值模拟非常具有挑战性，且缺乏解析解甚至近似解，这进一步使新器件的设计复杂化。本项目将发展基于边界积分方程方法的先进数值技术，并将其应用于模拟光子器件。与目前需要对设备进行体积网格化模拟的方法不同，该项目的方法只需要对设备的表面或边界进行网格化，从而显著减少了问题的规模，并显著提高了速度、CPU和内存效率。将使用高阶多项式函数来近似电磁未知数，导致相对于网格尺寸的精确解的收敛速度几乎是指数级的，与目前只能实现线性或二次收敛的方法相反。将设计并实现一个优化框架，该框架将能够自动设计新的，准备制造的光子器件，除了所需功能和性能的规格外，无需任何人为干预。然后，利用该框架设计和评估真实的硅光子器件，如波长解复用器、功率分配器和光栅耦合器，来证明新的仿真和优化平台的有效性。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。
