“…In this work, we aim to obtain all-optical logic gates under the mode on-off keying (OOK) switching using the powerful technology of photonic crystals (PhC's) with the versatility and usefulness of Mach-Zender interferometers (MZI's). This method (on-off keying -OOK) used for obtaining optical contrast level has brought remarkable results in all-optical logic gates field [10,[15][16][17], hence it makes an excellent opportunity for scientific research.…”

“…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.…”

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.

“…PM-PCFs have two orthogonally polarized core modes which act as two different optical paths for interference [52]. The two different optical paths can also be formed by two core modes in two-core PCFs [53,54], or two core fibers [55]. In addition, the core mode and cladding modes that are excited at the splicing region between a SMF and a PCF due to mode mismatch [56] or a collapsed region in PCFs [57][58][59][60][61][62].…”

Photonic crystal fibers (PCFs), also known as microstructured optical fibers, are a highlighted invention of optical fiber technology which have unveiled a new domain of manipulating light in engineered fiber waveguides with unparalleled flexibility and controllability. Since the report of the first fabricated PCF in 1996, research in PCFs has resulted in numerous explorations, development and commercialization of PCF-based technologies and applications. PCFs contain axially aligned air channels which provide a large degree of freedom in design to achieve a variety of peculiar properties; numerous PCF-based sensors have been proposed, developed and demonstrated for a broad range of sensing applications. In this chapter, we will review the field of research on design, development and experimental achievement of PCF-based interferometric sensors for physical and biomedical sensing applications.
