Broadband enhancement relies on precise tilt

If a photon source could be placed on a single chip and made to produce photons at a high rate, this could enable high-speed quantum communication or information processing. A simple on-chip photon source using a hyperbolic metamaterial is proposed, and investigators carried out calculations to show that a prototype arranged in a precise way can overcome problems of low efficiency and allow for high repetition rates for on-chip photon sources.
