Ultra-strongly sub-Poissonian light generation in a quantum dot-bimodal cavity system

We theoretically investigate the sub-Poissonian light generation in a cavity quantum electrodynamics system of a single quantum dot coupled a bimodal nanocavity. It is shown in a recent work [Arka Majumdar et.al, Phys. Rev. Lett. 108, 183601 (2012)] that the system can generate strongly sub-Poissonian light when one of the cavity modes is driven coherently and resonantly. We study the two-mode coherent driving regime of the coupled system. The effect of additional cavity mode driving on the statistic characteristics of photon emission is presented by evaluating the zero-delay second-order correlation function g2(0). We interpret the optimization of sub-Poissonian feature by regulating the ratio between driving strengths of two cavity modes and observe that g2(0) can be reduced up to several orders of magnitude (g2(0))<10-4), comparing with one-mode driving system (g2(0)~0.1), indicating ultra-strongly sub-Poissonian light generation.
