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 (beta(3)), 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.
