Abstract

We propose an all-optical logical gate based in a triple-core photonic fiber crystal operating with two ultrashort fundamental soliton pulses of 100 fs, with pulse amplitude modulation in the modality of amplitude shift keying (PAM-ASK) with binary amplitude modulation. In particular, we examine the performance of a triple-core PCF coupler to execute two-input logical functions. The pulse propagation is modelled by an extended nonlinear Schroedinger equation including the terms associated with the anomalous group-velocity dispersion (GVD) and the third-order dispersion β3, as well as the nonlinear effects of self-phase modulation (SPM), cross-phase modulation (XPM), self-steepening, and intrapulse Raman scattering (IRS) in a lossless configuration. Our results indicate the possibility of getting logical operations by controlling the phase difference between the input pulses.
