摘要

我们报道了在硅锗硅平台上的环形谐振器，工作在3.5-4.6µm的中红外波长范围内，质量因子高达一百万。制造技术的进步使我们能够展示如此高的q因子，这使硅锗处于中红外集成光子平台的前沿。通过观察顺时针（CW）和逆时针（CCW）共振之间的简并提升以及由于环中有效的功率积累而产生的光学双稳性，证明了高Q的实现。

One million quality factor integrated ring resonators in the mid-infrared

We report ring resonators on a silicon germanium on silicon platform operating in the mid-infrared wavelength range around 3.5–4.6 µm with quality factors reaching up to one million. Advances in fabrication technology enable us to demonstrate such high Q-factors, which put silicon germanium at the forefront of mid-infrared integrated photonic platforms. The achievement of high Q is attested by the observation of degeneracy lifting between clockwise (CW) and counter-clockwise (CCW) resonances, as well as optical bistability due to an efficient power buildup in the rings.
