Cavity Solitons (CSs) have an important role as information bits in all optical information processing. The Capabilities of excitable CSs were created to improve the possibilities in designing of all optical gates. In this paper, we switched on a new type of CS as Excitable Cavity Soliton in the Cavity Soliton Laser (CSL). Also, we designed logical gates (AND, OR) with excitable CSs in the CSL.
