title: All-optical NAND/NOT/AND/OR logic gates based on combined Brillouin gain and loss in an optical fiber.
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.
