“…However, NLS equations only have possible analytical solutions in very particular situations; therefore, simulations based on numerical methods are an essential tool to study in order to gain improvements in optical systems. In the literature, there are many works involving couplers and other fiber-based devices, where it is quite common to use numerical methods such as the fourthorder Runge-Kutta (RK4) [2], [3], [8], [9], the split-step Fourier Method (SSFM) [10]- [12] and the finite-differencetime-domain (FDTD) [4], [13]- [15]. However, such methods require extensive simulations and a large amount of data to be analyzed, which may hinder the interpretation of the obtained results.…”

“…Some authors use the nomenclature Tucker-3 for the thirdorder Tucker decomposition. When one of the matrix factors of this decomposition is equal to the identity matrix, for example A (1) = I I 1 , we say that we have a Tucker-2 model given by X = C × 2 A (2) × 3 A (3) , which is equivalent to a Tucker-(2, 3) decomposition. Similarly, when two of the matrix factors are equal to identity matrices, for example A (1) = I I 1 and A (2) = I I 2 , we have a Tucker-1, or Tucker-(1, 3) decomposition, and X becomes X = C × 3 A (3) .…”

Tensor models have been used extensively in signal processing applications to design different types of communication systems. This paper proposes, for the first time, the use of tensor models for optical communications. The signals of an optical dual-core coupler network are modeled as a multiway array (tensor), which satisfies a generalized Tucker train decomposition. This tensor model is then used to develop an estimation algorithm that enables the network parameters to be estimated from the input and output signals. The performance of this algorithm was evaluated by means of computer simulations, in terms of NMSE of the estimated parameters and convergence speed. For the tested configurations, good levels of NMSE with fast convergence were obtained, demonstrating the effectiveness of the proposed method as a promising tool for studying and designing optical devices, with a wide range of applications in the context of lightwave systems.

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.
