摘要:

集成光隔离器一直是光子集成电路(PIC)的一个长期挑战。一个理想的PIC集成光隔离器应该是由单片工艺制成,具有小的足迹,表现出宽带和偏振多样性的操作,并与多种材料平台兼容。尽管取得了重大进展,但迄今为止报道的光隔离器并不能满足所有这些要求。在这篇文章中,我们提出了单片集成的宽带磁光隔离器的硅和氮化硅(SiN)平台上的TE和TM模式操作具有创纪录的高性能,满足PIC应用的所有基本特性。特别是,我们展示了完全TE宽带隔离器,通过沉积高品质的磁光石榴石薄膜的侧壁上的Si和SiN波导,TE偏振片上激光器和放大器的应用程序的关键结果。这项工作演示了单片集成的高性能光隔离器的偏振多样性硅光子系统的芯片,使新的途径,赋予非互易光子功能的各种集成的光子器件。

英文摘要:

Integrated optical isolators have been a longstanding challenge for photonic integrated circuits (PIC). An ideal integrated optical isolator for PIC should be made by a monolithic process, have a small footprint, exhibit broadband and polarization-diverse operation, and be compatible with multiple materials platforms. Despite significant progress, the optical isolators reported so far do not meet all these requirements. In this article we present monolithically integrated broadband magneto-optical isolators on silicon and silicon nitride (SiN) platforms operating for both TE and TM modes with record high performances, fulfilling all the essential characteristics for PIC applications. In particular, we demonstrate fully-TE broadband isolators by depositing high quality magneto-optical garnet thin films on the sidewalls of Si and SiN waveguides, a critical result for applications in TE-polarized on-chip lasers and amplifiers. This work demonstrates monolithic integration of high performance optical isolators on chip for polarization-diverse silicon photonic systems, enabling new pathways to impart nonreciprocal photonic functionality to a variety of integrated photonic devices.
