An even more versatile optical chip

Telecommunication networks will soon reach the physical limits of current technology and in order to overcome the current bottleneck, they will have to exploit the quantum properties of light. Roberto Morandotti and his INRS team are paving the way to this technological revolution by removing the technical barriers of quantum photonics through the use of their optical chips. Recently they directly generated cross-polarized (orthogonal) photon pairs on a chip, a first in quantum optics. Polarizat...
