Nanophotonic integrated circuits (NPICs) enable the realization of complex optical functionalities on a chip by joining waveguide-based components with full-fledged planar optical systems. When waveguiding materials with high refractive index contrast are employed, strong optical confinement allows for creating compact photonic circuits with small footprint and sub-wavelength features. By employing established fabrication techniques originally developed for the realization of integrated electrical circuits, these devices can be fabricated with high yield and reproducibility with potential for mass-market applications. NPICs find in particular widespread use for chipscale sensing and metrology, optical signal processing and also data communication with high bandwidth in optical interconnects.The most widely used silicon-based NPICs are predominantly passive devices when realized in a monolithic material system. The lack of active functionality, however, precludes realizing fully integrated systems which contain light sources, light detectors and routing elements, as required especially for functional circuits. To overcome these limitations, in this project, we will provide active functionalities to such passive inorganic material systems through hybrid integration with functional organic materials based on anthracene derivatives and co-crystals, to enable a new class of NPICs, as well as for providing new tools to study light-matter interactions.We will combine nanophotonic circuits based on broadband transparent silicon nitride with organic emitters by embedding molecular light sources directly into the near field of waveguide devices. Through evanescent coupling, strong interaction of the organic emitter with the underlying inorganic photonic architecture will allow for efficient light extraction into the nanophotonic circuitry. Using the rich toolbox of nanophotonics, cavity-enhanced coupling will provide tailored emission properties for spectral applications in the visible wavelength range. In addition, nanophotonic elements will be used for optical processing of the emitted signal directly on the chip and thus allow for all-photonic light source implementations with nanoscale footprint. We will study the performance of waveguide integrated light sources both in the high intensity regime, as well as in the few photon regime at cryogenic temperatures to investigate their suitability for single photon emission. The temporal analysis will be carried out on-chip using superconducting single photon detectors with high timing resolution. In combination with high performance on-chip filter elements, a powerful platform will be created to analyze the properties of hybrid inorganic-organic photonic systems with high timing resolution and sensitivity. The platform developed within this project will serve as a prototype scalable testbed for investigating light-emitting molecules and provide the tools for studying few photon statistics on a chip.

纳米光子集成电路（NPIC）通过将波导基组件与成熟的平面光学系统结合在一起，能够在芯片上实现复杂的光学功能。当采用具有高折射率对比度的波导材料时，强光学约束允许创建具有小覆盖区和亚波长特征的紧凑光子电路。通过采用最初为实现集成电路而开发的已建立的制造技术，这些器件可以以高产率和再现性制造，具有大众市场应用的潜力。NPIC在芯片级传感和计量、光信号处理以及光互连中的高带宽数据通信方面有着特别广泛的用途。然而，有源功能的缺乏排除了实现包含光源、光检测器和路由元件的完全集成的系统，如功能电路特别需要的。为了克服这些限制，在本项目中，我们将通过与基于蒽衍生物和共晶的功能有机材料的混合集成，为这种无源无机材料系统提供有源功能，以实现一类新的NPIC，以及提供研究光的新工具-我们将通过嵌入分子光，将基于宽带透明氮化硅的联合收割机纳米光子电路与有机发射器结合起来，源直接进入波导设备的近场。通过消逝耦合，有机发射体与底层无机光子结构的强烈相互作用将允许高效地将光提取到纳米光子电路中。利用丰富的纳米光子学工具箱，腔增强耦合将为可见波长范围内的光谱应用提供定制的发射特性。此外，纳米光子元件将用于直接在芯片上对发射的信号进行光学处理，从而允许实现具有纳米级足迹的全光子光源。我们将研究波导集成光源的性能，无论是在高强度制度，以及在低温下的几个光子制度，以调查其适用于单光子发射。时间分析将在芯片上进行，使用超导单光子探测器具有高时序分辨率。结合高性能片上滤波器元件，将创建一个强大的平台来分析具有高时序分辨率和灵敏度的混合无机-有机光子系统的特性。在该项目中开发的平台将作为研究发光分子的原型可扩展测试平台，并提供研究芯片上少数光子统计的工具。
