Abstract

A combined Brillouin gain and loss process has been proposed in a polarization maintaining optical fiber to realize all-optical NAND/NOT/AND/OR logic gates in the frequency domain. A model describing the interaction of a Stokes, anti-Stokes, and continuous wave and two acoustic waves inside a fiber, ranging in length from 350–2300 m, was used to theoretically model the gates. Through the optimization of the pump depletion and gain saturation in the combined gain and loss process, switching contrasts of 20%–83% have been simulated for different configurations.
