We investigate and demonstrate a model to engineer photon blockade in a quantum-dot-coupled dual micro-ring resonator system mediated by the Vernier effect which arises from the radius mismatch between the two resonators. The Vernier effect induced resonance detuning, which serves as an effective and highly tunable mechanism for controlling destructive quantum interference and nonlinear photon transport within the quantum system. The Vernier effect provides an additional degree of freedom for tailoring and enhancing photon blockade beyond conventional cavity quantum electrodynamics mech anism. Our findings demonstrate that the Vernier-induced detuning significantly improves the tunability, controllability, and robustness of nonclassical light generation in integrated photonic platform.
