In this paper we propose all-optical binary to decimal converter with dark-bright soliton conversion control. The input logic '0' and '1' are performed by dark and bright soliton, respectively. By using the dark-bright soliton conversion behavior with in the π/2 phase shift device, we can use the drop and though port output for represent decimal number output for each binary input. This is a simple and flexible scheme for performed logic switching system, which can be used in advanced complex logic.
