Fig. 4: Heralded single-photon emission.
From: Ultra-efficient generation of time-energy entangled photon pairs in an InGaP photonic crystal cavity
Heralded second-order correlation function showing a \({g}_{h}^{(2)}(0)=0.17\pm 0.02\); measured at pump power in the cavity P0 = 36 μW. The shaded region corresponds to 1 standard deviation.
