We describe a delay-based optical device for solving the the Satisfiability problem. The device has a graph structure which is traversed by light in order to generate a solution. The device has 2 special nodes: a start node (where the initial pulse is sent) and a destination node (where the solution is read). Multiple signals are expected at the destination. Some of them contain valid solutions and others do not. A special, time filter, is proposed in order to detect a solution. Graphical simulations show how the device works.
