在过去的十年中，基于芯片的非线性光子器件在近红外和中红外区域的经典和量子应用方面取得了显着的进展。然而，在可见光和近可见光范围内实现的演示很少，主要是由于大的正常物质群速度色散（GVD），这使得相位匹配三阶参数过程具有挑战性。在本文中，我们表明，利用色散工程的高阶波导模式提供波导色散，允许小或异常的GVD在可见光和近可见的制度和相位匹配的四波混频过程。我们通过在氮化硅微谐振器中演示近可见的锁模克尔频率梳和与Rb跃迁兼容的窄带光子对源来说明这个概念的力量。这些实现将非线性光子学的应用扩展到可见光和近可见光区域，用于时间和频率计量、光谱校准、量子信息和生物医学应用。
Over the past decade, remarkable advances have been realized in chip-based nonlinear photonic devices for classical and quantum applications in the near- and mid-infrared regimes. However, few demonstrations have been realized in the visible and near-visible regimes, primarily due to the large normal material group-velocity dispersion (GVD) that makes it challenging to phase match third-order parametric processes. In this paper, we show that exploiting dispersion engineering of higher-order waveguide modes provides waveguide dispersion that allows for small or anomalous GVD in the visible and near-visible regimes and phase matching of four-wave mixing processes. We illustrate the power of this concept by demonstrating in silicon nitride microresonators a near-visible modelocked Kerr frequency comb and a narrow-band photon-pair source compatible with Rb transitions. These realizations extend applications of nonlinear photonics towards the visible and near-visible regimes for applications in time and frequency metrology, spectral calibration, quantum information, and biomedical applications.
