In our investigation, the input pulses are in the fundamental soliton propagation regime.…”

“…In this work, we considered the propagation of pulses from the order of femtosecond, thus it is necessary to use the nonlinear Schrödinger equation described in (2.1). We have to analyze the high-order nonlinear effects such as self-steepening (SS) and intrapulse Raman scattering (IRS) [29,30]. The dispersion of third order (b 3 ) must be added in dispersive effects.…”

“…In [9] was made the correction in the term referring to the coupling coefficient dispersion and it was found that this term being much shorter than one meter is sufficient to cause significant distortion for ultrashort input pulses. After these two papers, investigations have been made to some applications in all-optical logic gates.…”

In this work, we present a numerical investigation of the asymmetric double nonlinear coupling of photonic crystal fibers in an on‐off switch to obtain fully optical logic gates. Ultra‐short pulses (100 fs) are propagated through the device in three distinct excitation power regimes, power below critical (Po = 72 kW, where Po represents the excitation power of the device), critical power (Pc = 103.5 kW, where Pc represents critical Power for which the power switching is 50% for both guides. There are cases where Po is above the critical value, there are cases that is below), and power above critical (Po = 110 kW). The pulse switching characteristics are analyzed as a function of the input power and the nonlinearity profile (β‐beta) inserted in one of the component guides. The nonlinearity profiles follow the regimes: constant, increasing and decreasing, and high order effects, such as third‐order dispersion, intrapulse Raman scattering and self‐steepening are included in the generalized Schrödinger nonlinear equation governs the pulse propagation dynamics. The results show that the proposed device can be used to obtain AND, OR, and NOT logic gate. Numerical studies were done from the coupled‐coupled equations solved using the fourth‐order Runge‐Kutta method, using MATLAB as a programming tool for solving equations. The implementation of fully optical logic gates tends to revolutionize new digital systems in the field of data storage, such as optical memory, “replacement” of electronic circuits among other applications. Optical systems have a great advantage as they are free from electromagnetic interference and have high rates of data transmission.
