Abstract
In this work we present a scheme based on the complementary behavior of the two effective parameters in Cavity Soliton switching process by which it is possible to design logic gates, namely “OR” and “AND”. By considering two independent writing beams, it is shown that by properly adjusting the amplitude and duration of switching pulses, “AND” and “OR” logical operations can be carried out. Specifically, the output of the system, which is the on or off state of the Cavity Soliton, is determined according to the inputs of the system which depend on the type of desired operation. The simulations show that these processes take place in a time scale of less than a nanosecond. The cascadibility of these gates is also studied.
