Hybrid lithium niobate on insulator quantum photonic integrated circuit (C08*)

在本计画中，我们将探索以绝缘体上的锂氧化物薄膜（LNOI）作为量子光子积体电路的材料平台。在将腔耦合InAs量子点转印到LNOI电路上之后，我们将使用周期性极化LNOI波导结构对量子点按需产生的光子进行片上频率转换。这将为我们提供电信C波段的按需不可区分的单光子，这是基于光纤的量子通信的宝贵资源。

In this project, we will explore thin-film lithium niobate on insulator (LNOI) as the material platform for quantum photonic integrated circuits. After transfer printing of cavity coupled InAs quantum dots onto a LNOI circuit, we will on-chip frequency convert the on-demand generated photons from the quantum dot using a periodically poled LNOI waveguide structure. This will provide us with on-demand indistinguishable single photons at the telecom C-band, which are a valuabe resource for fiber-based quantum communication.
