In this paper we study the switching of Bright and Dark solitons in an array of coupled active lasing cavities with Kerr nonlinearity, that excite by an incident pump field. In this way, first we introduce a model equation explaining propagation of light in this medium (discrete nonlinear Schrödinger equation) and parameters of that, then obtain the homogeneous and inhomogeneous solutions of this system. In continuous, we specify the existence of Bright and Dark solitonic branches by obtaining stability regions of inhomogeneous solutions on bistability curve by numerical simulations. At the end of this work, we study the possibility of switching of Bright and Dark solitons in this system by inject a Gaussian beam with proper amplitude and width and sufficient injection time into considered array of cavities.

Keywords: bright and dark solitons, lasing medium, coupled cavities, stability, switching
