Quantum optics technology sends more data down optical fibre

French start-up CaiLabs uses ‘multi-plane light conversion’ to expand the capacity of optical fibre. The company is currently selling optical components developed with the help of Alcatel Lucent and is now working with other partners “to introduce the technology into optical network equipment”, says CEO and founder-inventor Jean-Francois Morizur. The idea was pitched at the 2015 ACES awards for academic enterprise in Barcelona.
