Abstract

We theoretically propose a scheme for photon blockade in a cavity quantum electrodynamical system consisting of an N-type atomic medium interacting with a single-mode Fabry-Perot cavity. In contrast to inefficient nonlinear-dispersion-induced photon blockade suppressed by a large detuning, the photon blockade in our scheme is induced by a large nonlinear dissipation of the cavity created by the N-type atomic system. A deep photon blockade is manifested with a vanishing equal-time second-order correlation function within the cavity linewidth. This work provides an efficient photon blockade because it work in the near-resonance case.
