(a) The maximal single-photon probabilities \(P_{1,\max }^{\textrm{ogbm}}\) and (b) the normalized second-order autocorrelation function \(g^{(2)}_{\textrm{ogbm}}\) for SPSs based on OGBMs as functions of the number of multiplexed units N for the transmission coefficients \(V_t=0.985\) and \(V_r=0.99\), and for various values of the detector efficiency \(V_D\).
