“…All-optical logic gates and flip-flops are other fundamental elements for optical computing [ 22 ], even if still, at the beginning of the last decade, there were doubts about their feasibility and their possibility of competing with microelectronics [ 144 ]. Such skepticism was not fully justified, even if, still five years later, realization of an all-optical flip-flop required coupling two optical triode switches made by a nonlinear étalon and gradient-index lenses [ 19 ]; to date, however, several all-optical logic devices have been demonstrated [ 13 , 25 , 27 , 145 , 146 , 147 , 148 ].…”

The combination of integrated optics technologies with nonlinear photonics, which has led to growth of nonlinear integrated photonics, has also opened the way to groundbreaking new devices and applications. In a companion paper also submitted for publication in this journal, we introduce the main physical processes involved in nonlinear photonics applications and discuss the fundaments of this research area. The applications, on the other hand, have been made possible by availability of suitable materials with high nonlinear coefficients and/or by design of guided-wave structures that can enhance a material’s nonlinear properties. A summary of the traditional and innovative nonlinear materials is presented there. Here, we discuss the fabrication processes and integration platforms, referring to semiconductors, glasses, lithium niobate, and two-dimensional materials. Various waveguide structures are presented. In addition, we report several examples of nonlinear photonic integrated devices to be employed in optical communications, all-optical signal processing and computing, or in quantum optics. We aimed at offering a broad overview, even if, certainly, not exhaustive. However, we hope that the overall work will provide guidance for newcomers to this field and some hints to interested researchers for more detailed investigation of the present and future development of this hot and rapidly growing field.

“…According to their predominant electromagnetic response, materials or structures with near-zero parameters at a given frequency can be classified as epsilon-near-zero (ENZ), ε ∼ = 0; mu-near-zero (MNZ), µ ∼ = 0; and epsilon-and-mu-near-zero (EMNZ), ε ∼ = 0 and µ ∼ = 0 media. All aforementioned classes exhibit a near-zero index of refraction n = √ εµ ∼ = 0 at the frequency of interest and can be jointly addressed as zero-index media [147][148][149][150].…”

“…These materials or structures empower two of the main requirements to boost the nonlinear response of matter: phase matching [150] and high field intensities. Structures with nearzero parameters can provide large field intensity enhancements over large regions, while simultaneously providing phase matching [147][148][149][150]. ENZ materials are becoming a platform to obtain non-classical, non-reciprocal, and non-local responses of matter [147][148][149][150].…”

ENZ materials are becoming a platform to obtain non-classical, non-reciprocal, and non-local responses of matter [147][148][149][150]. ENZ structures loaded with nonlinear media are particularly well suited to enable the coherent superposition of nonlinear effects over long distances, leading to enhanced nonlinear effects, in particular, Kerr nonlinearity, SHG, THG, and FWM [147][148][149][150].…”

All-optical logic gates (AO-LGs) are the key elements that play a pivotal role in the development of future all-optical networks and all-optical computing. A complete overview of the seven all-optical logic gates (i.e., AND, OR, NOT, XOR, XNOR, NAND, and NOR) based on their design techniques and applications are covered, including the latest technologies, such as topological photonics and artificial intelligence-based designs techniques. In addition, we have further categorized the AO-LGs as reconfigurable gates, simultaneous gates, reversible gates, modulation-based gates, and data rate-based gates. The techniques to implement these different classes of gates are reviewed and their limitations are discussed. We also discuss in brief the various simulation tools used to design and analyze the AO-LGs. Finally, the most feasible techniques for constructing optical integrated circuits based on the existing fabrication technologies and available resources are explored, and future prospects are outlined.
