Fig. 3: Single photon emission measured via ultra low-loss waveguide.
From: Ultra-low loss quantum photonic circuits integrated with single quantum emitters
a Quantum dot photoluminescence (PL) spectrum from a hybrid device pumped non-resonantly at 841.5 nm, showing three transitions from the same QD. b PL intensity for X0 as a function of input power. Red dot: pump level for measurements in c. The uncertainties represent 95% confidence intervals computed from a Lorentzian fit to the QD emission line intensity. c Second-order correlation for the X0 line pumped at saturation, showing triggered single photon emission with fitted g(2)(0) = (0.07 ± 0.03) at zero delay. All uncertainties reported are 95% fit confidence intervals, corresponding to two standard deviations.
