SGER: Monolithically Integrated Garnet Isolators on Si

摘要本提案包括研究和教育目标，涉及将磁光石榴石隔离器集成到Si上，初步应用于近红外波长的电信。这项研究将对光子集成电路（PICs）和光电集成电路（OEICs）的应用产生广泛的影响，例如光计算和互连。石榴石的集成还将进一步实现其他非互易器件，如模式转换器和环行器，并且集成技术将可转移到其他半导体平台，如InP和GaAs。智力优势：将石榴石与半导体平台集成一直被认为是不可能的。然而，PI最近开发了一种将石榴石与半导体集成的技术。在目前的提案中，这种新技术将应用于使用两种设计的第一个集成石榴石器件。这里开发的原型将是第一个在半导体平台上实现的石榴石核心旋转器。石榴石波导隔离器中传统的双折射障碍将通过磁芯形状调谐来克服。此外，一种同时使用面内偏磁和垂直偏磁的新方法将有助于对PIC和OEIC社区的新理解。更广泛的影响：该项目将促进发现和理解，同时通过研究生培训、行业互动和本科生研究促进教学、培训和学习。它还将通过先进的光互连、光计算和电信技术造福社会。这个项目真正实现了？缺失的环节?在光子学中，利用这一探索性工作，第一代光源可以与光子集成电路和光电子集成电路集成。

AbstractThis proposal includes research and educational goals involving the integration of magnetooptical garnet isolators onto Si with the initial application being telecommunications at near infrared wavelengths. This research will have a broad impact on photonic integrated circuits (PICs) and opto-electronic integrated circuits (OEICs) for applications such as optical computing and interconnects as well. The integration of garnet will also further the realization of other nonreciprocal devices such as mode converters, and circulators, and the integration techniques will be transferable to other semiconductors platforms, such as InP and GaAs.Intellectual Merit:The integration of garnet with semiconductor platforms has long been thought impossible. However, the PI has recently developed a technique for the integration of garnet with semiconductors. In the current proposal, this novel technique will be applied to the first integrated garnet devices using two designs. The prototypes developed here will be the first rotators with garnet cores that have been realized on semiconductor platforms. The traditional roadblock of birefringence in garnet waveguide isolators will be overcome with core shape tuning. Also, a novel approach of using both in-plane and perpendicular magnetic biasing will contribute new understanding to the PIC and OEIC communities. Broader Impact:This project will advance discovery and understanding while promoting teaching, training, and learning through graduate student training, industrial interaction, and undergraduate research. It will also benefit society through advances optical interconnects, optical computing, telecommunications. This project truly enables the ?missing link? in photonics such that first generation light sources can be integrated with photonic integrated circuits and optoelectronic integrated circuits using this exploratory work.
