The existence, dynamics and switching of bright and dark spatial soliton in coupled active cavities array above lasing threshold in presence of population inversion are studied here. Different types of discrete cavity soliton lasers are introduced and their stability is analyzed, together with the comparison of population inversion effects on bright and dark solitons. The effects of injection time, intensity, width, and phase difference of switching beam are analyzed to perform a successful ON/OFF switching.
