Silicon carbide (SiC) is rapidly emerging as a leading platform for the implementation of nonlinear and quantum photonics. Here, we find that commercial SiC, which hosts a variety of spin qubits, possesses low optical absorption that can enable SiC integrated photonics with quality factors exceeding ${10^7}$. We fabricate multimode microring resonators with quality factors as high as 1.1 million, and observe low-threshold ($8.5 \pm 0.5\;{\rm mW} $) optical parametric oscillation using the fundamental mode as well as optical microcombs spanning 200 nm using a higher-order mode. Our demonstration is an essential milestone in the development of photonic devices that harness the unique optical properties of SiC, paving the way toward the monolithic integration of nonlinear photonics with spin-based quantum technologies.

碳化硅纳米光子学中的光学参量振荡

碳化硅(SiC)迅速成为实现非线性和量子光子学的领先平台。在这里,我们发现拥有各种自旋量子位的商用SiC具有低光吸收,可以使SiC集成光子的品质因数超过$ {10 ^ 7} $。我们制造质量因子高达110万的多模微环谐振器,并观察到低阈值($ 8.5 \ pm 0.5 \; {\ rm mW} $)使用基本模式的光学参量振荡以及使用高阶模式的200 nm的光学微梳。我们的演示是开发利用SiC独特光学特性的光子器件的重要里程碑,为非线性光子与基于自旋的量子技术的单片集成铺平了道路。
