We theoretically investigate the photon statistics in a cavity quantum electrodynamics system of single dot (QD) coupled to photonic molecule. Our previous work [Wen Zhang et.al, Phys. Rev. A 89, 043832 (2014)] has shown that QD-bimodal can generate ultrastrongly sub-Poissonian light by regulating ratio between driving strengths two modes. Here we study single-mode nanocavities with QD coupling one them as molecule system. Statistical character emission is presented evaluating zero-delay secondorder correlation function g²(0). When both cavities with/without are driven, be optimized each cavities. also present dependences other parameters on statistics. The physical mechanism effects optimize combination super-Poissonian and coherent which results generation. As result g²(0) reduced up several orders magnitude compared one-mode-cavity
