Scalable Two-Dimensional Quantum Integrated Photonics


Summer School

At half time of our project we will organize summer school on 2D materials for PhD and young researchers. We will invite experts on 2D materials from outside of our consortium.


Setup a consortium homepage to present our research to the public and use it to coordinate events.

Fabrication of large-scale circuits

Nanofabrication of large-scale photonic waveguide circuits consisting passive and active circuit elements.

Optimize circuit design

We optimize the design of photonic integrated circuits for 2D material integration using finite-difference time-domain and beam propagation simulations.

Deterministic integration

Highly stable 2D materials (e.g. WSe2, MoSe2, InSe, hBN, black Phosphorus) will be exfoliated, encapsulated and transferred to photonic chips.

Data Management Plan – Draft

We take part in the Open Research Data Pilot and thus we will take care of making our data available and prepare a draft for our data management plan.
