Abstract

We demonstrate unconventional photon blockade in a symmetric Kerr dimer driven with equal-amplitude fields at a 90∘ phase difference. The minimum intercavity coupling is Jmin=γ/4 at a Kerr nonlinearity U≪γ achievable in standard photonic molecules. The quadrature-driven site emits strongly antibunched light with a smooth, oscillation-free second-order correlator directly resolvable with standard detectors. The scheme operates under continuous-wave and pulsed excitation, and fabrication disorder can be fully compensated by retuning the drive phase and amplitude ratio, removing the need for postfabrication cavity trimming.
