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

• Subject Area: Experimental Condensed Matter Physics
• Term: since 2022
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 231447078

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.
