Integrated on-chip quantum light sources on a van der Waals platform
Researchers integrated quantum light sources onto a van der Waals platform by combining strain-engineered bilayer WSe2 emitters with multimode WS2 waveguides. This created an efficient, integrated single-photon source where both the emitter and photonic circuitry are made from vdW materials, paving the way for scalable photonic quantum information processing.
