We calculate that an appropriate modification of the field associated with only one of the
photons of a photon pair can suppress generation of the pair entirely. From this general …

We report the generation of high-purity twin photon pairs through cavity-enhanced non-
degenerate four-wave mixing (FWM) in a high-Q silicon microdisk resonator. Twin photon …
