Imec and MIT integrate single photon emitters in 2D materials

Imec researchers at Ghent University and MIT have integrated single photon emitters in 2D layered materials with a Silicon Nitride photonic chip.  Even for moderate quantum yields, dielectric cavities could be designed such that the single photon extraction into the guided mode can reach unity.  The results provide a crucial step in fundamental quantum photonics ...
