论文摘要
在未来的光子集成电路对量子信息和传感的情况下，用于综合光子学的多功能和新型材料平台的开发至关重要。在这里，我们提出了一个基于高反射指数硅氧硝基（\ ce {sion}）的低损坏材料平台，该平台在各种红色/近膜波长范围内为线性和非线性光学应用提供了重要特性。可见波长的已证明的传播损失$ <1.5 $ 〜db/cm，可以实现长而复杂的电路用于光子操作，以及实现高质量因子谐振器的实现。此外，提议的\ ce {sion}显示了高的非线性系数为$ 10^{ - 19} $ 〜m $^2 $/w，提高了在芯片光子生成方案中可利用的非线性效应的强度。
The development of versatile and novel material platforms for integrated photonics is of prime importance in the perspective of future applications of photonic integrated circuits for quantum information and sensing. Here we present a low-loss material platform based on high-refractive index silicon oxynitride (\ce{SiON}), which offers significant characteristics for linear and non-linear optics applications in a wide range of red/near-infrared wavelengths. The demonstrated propagation loss $<1.5$~dB/cm for visible wavelengths enables the realization of long and intricate circuitry for photon manipulations, as well as the realization of high quality factor resonators. In addition, the proposed \ce{SiON} shows a high nonlinear coefficient of $10^{-19}$~m$^2$/W, improving the strength of nonlinear effects exploitable for on-chip photon generation schemes.
