In this work, a numerical analysis to obtain gates in coupler symmetrical nonlinear (NLDC) in photonic crystal fibers (PCF), which in cross section is formed with periodic array of air holes, operating in light pulse ultrashort as solitons, lasting 100fs (fentosegundos). The pulses in pulse amplitude modulation formats were investigated (WFP), with amplitude shift keying (ASK), in order to obtain logic gates in the triple NLDC PCF-planar symmetrical. In this paper we use double couplers fiber optic in setting up a Mach-Zenhder Interferometer to build a current sensor, its functionality is applied to investigate the quality alternating current, whether in the generation, transmission or distribution of electricity. Since the interferometer of Mach-Zenhder uses a mechanical agent, agent will use the same for constructing the current sensor constituted of a piezoelectric. In making the comparison of the two sensors, we can allocate its usability in different consumers
