Description
Summary:	•Here, we focus to the excitable CS in the cavity with saturable absorber without holding beam.•We remove the holding beam, it reduces spatial volume of system and increase flexibility of system.•We switch on excitable CS and then it is compared with stable and self-pulsing CSs.•The logic gates (AND and OR) has been proposed by using of excitable CSs. Cavity solitons (CSs) have an important role as information bits in all optical information processing. In this paper, we switched on a new type of CS as excitable cavity soliton in the cavity soliton laser (CSL). Also, we compared the behavior of excitable CS with self-pulsing and stable CSs by using of suitable values for system parameters and then we designed logical gates (AND, OR) with excitable CSs in the CSL. The capabilities of excitable CSs has been studied to improve possibilities for designing of all optical gates.
