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.

在这个项目中，我们将探索薄膜绝缘体上的LiNbate(LNOI)作为量子光子集成电路的材料平台。在将腔耦合的InAs量子点转移到LNOI电路上后，我们将使用周期性极化的LNOI波导结构对量子点按需产生的光子进行片上频率转换。这将在电信C波段为我们提供按需的不可区分的单光子，这是基于光纤的量子通信的宝贵资源。
