Abstract
We demonstrate ultra-broadband spontaneous parametric down-conversion over a 100 THz bandwidth using an on-chip dispersion-engineered periodically-poled lithium niobate waveguide. The source produces photon-pairs with an unprecedented 13 GHz/mW efficiency and a coincidence-to-accidental ratio exceeding 105.
