“…On the other hand, the development of all-optical (AO) logic technologies is fundamental to realize future telecommunication networks with the exponential growth of internet traffic. Several waveguides, including photonic crystal waveguides, 2 – 9 semiconductor platforms, 10 – 14 gold nanowire waveguides, 15 metal slot waveguides, 16 metal–insulator–metal structures, 17 dielectric–metal–dielectric design, 18 dielectric–loaded waveguides, 19 graphene–containing compact microdisks, 20 and optical amplifiers, 21 have been used to create AO logic gates in recent years. The majority of these published designs only used photonic crystals to realize one or, at most, two logic gates, 2 – 13 in contrast to the suggested waveguide, which simultaneously realized seven logic operations.…”

.Silicon waveguides are particularly appealing for the implementation of all-optical (AO) signal processing devices and switches due to the improved fabrication technology of silicon. Therefore, a silicon-on-silica waveguide is employed as the building block for simulating fundamental AO logic operations, including XOR, AND, OR, NOT, NOR, NAND, and XNOR, at 1.33-μm telecommunications wavelength. The proposed waveguide consists of two microring resonators and three strip waveguides. The operation concept of these logic gates relies on the constructive and destructive interference that results from the phase difference induced by incident optical beams. The performance of the target logic gates is assessed against the contrast ratio (CR) metric. The simulation results suggest that, by exploiting the proposed waveguides, these gates can operate with higher CR and faster speed compared to other designs.

“…In the earlier days, semiconductor based transistors served the need of electronics. It often sits back due to limitations like low speed, high power consumption and heat dissipation (Cotter et al 1999;Priya et al 2021). Having eliminating these, photonic evolved with high speed communication by replacing electrons with photons (Tang et al 2010;Holmgaard et al 2007; Wu et al 2004).…”

All-optical devices are proven to have broad range of applications in the areas of communication. These devices form the basic building blocks of complex integrated circuits. By integrating these devices in the elds like signal processing, chip designing and network computations, a much more e cient device can be achieved. The design of all-optical logic gates like NAND, NOR and XNOR using plasmonic based Y-shaped power combiner is implemented in this paper work. The concept of linear interference is applied in the combiner to achieve the desired logic gates. The work is simulated and analysed using Finite-Difference Time Domain (FDTD) method, which is valuated using MATLAB. The present work ts under the area of 60 µm 2 which is smaller than the existing structures. The insertion loss, transmission e ciency and extinction ratio parameters are calculated and compared to variety of other designs.

“…Photons with their unique properties are very convenient carrier of information. Thus they actively can be applicable for designing various logic devices based on different physical phenomena [15][16][17][18]. Photons with magnetooptical features also seems very flexible for future applcations.…”

The results of studying the possibilities of the properties of magneto-optical qubits obtained using the Faraday rotation effect are presented. Waveguide geometries have been chosen for the design of various information processing and transmission devices based on new concepts creating key elements of logic gates, with new architectures applicable to different fields of science and industry. A mechanism for controlling magneto-optical qubits could be implemented for modeling of several magneto optical logic elements in waveguide forms, including simultaneous parallel AND, XOR and other procedures The proposed device can be used to create a wide range of information processing and transmission components founded on new strategies.
