摘要:

我们展示了铌钛氮化物超导纳米线图案化学计量氮化硅波导检测可见光和红外光子。在硅衬底上的绝缘体上使用氮化硅使我们能够同时实现可见光和红外线的光子电路,并将它们与纳米线检测器直接集成在芯片上。通过在该材料平台中实现行波检测器几何形状,我们实现了两种波长范围的高效单光子检测。我们的探测器是集成量子光学器件的理想选择,因为它们在宽带透明波导材料上提供了至关重要的功能。

英文摘要:

We demonstrate niobium titanium nitride superconducting nanowires patterned on stoichiometric silicon nitride waveguides for detecting visible and infrared photons. The use of silicon nitride on insulator on silicon substrates allows us to simultaneously realize photonic circuits for visible and infrared light and integrate them with nanowire detectors directly on-chip. By implementing a traveling wave detector geometry in this material platform, we achieve efficient single photon detection for both wavelength regimes. Our detectors are an ideal match for integrated quantum optics as they provide crucial functionality on a wideband transparent waveguide material.
