Owing to the advanced fabrication technology of silicon, silicon waveguides are particularly attractive for implementing all-optical signal processing devices and switches. Therefore, in this paper, a silicon-on-silica waveguide that consists of four slots arranged in the shape of the letter E is proposed to be employed as the building block for simulating fundamental all-optical logic gates, including XOR, AND, OR, NOT, NOR, NAND, and XNOR, at 1.55 μm telecommunications wavelength. The operation concept of these logic gates relies on the constructive and destructive interference that results from the phase difference induced by optical beams that are incident on the E-shaped waveguide. The performance of the target logic gates is assessed against the contrast ratio (CR) metric. The simulation results suggest that, by exploiting the E-shaped waveguides, these gates can operate with higher CR and faster speed compared to other designs.

“…AO-NOR, AND, and OR gates were experimentally demonstrated at 100 Gbps using a single SOA along with an optical filter wherein reconfigurability was achieved by deployment of CW light and tuning of the optical bandpass filter at SOA output. 80 The experimental setup for The variation of input wavelengths or phase control provided the required reconfigurability. 81 A Si photonic crystal-based compact structure operated as AO-XOR/NOT gate based on a fixed bias signal.…”

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.

“…By deploying or not deploying continuous wave (CW) light at the input of SOA and adjusting the tunable optical band-pass filter (OBPF) at the output of SOA, logic can be easily reconfigured. 22 A design method of all-optical logic NOT gates using two 3 dB couplers and two SOAs was proposed. This scheme has the advantages of a simple structure, few components, and the ability to achieve signal regeneration while completing logic functions.…”

We proposed a new and simple scheme to implement exclusive OR (XOR) and not exclusive OR (NXOR) logic operations in the optical domain enabled by a dual-parallel phase modulator (PM). Both the intensity and phase of the optical signal are utilized to represent the four different states of two binary inputs, and direct detection is used to map the four states to the corresponding binary output. Through numerical analysis, two PMs with phase offsets were adjusted to π∕2, and the phase shifter between the two PMs was controlled atπ∕2; thus, the NXOR logic gate was successfully carried out. Two PMs with phase offsets were adjusted to π∕2, and the phase shifter between the two PMs was controlled atπ; thus, the XOR logic gate was successfully carried out. Simulations were successfully carried out at the speed of 10 Gb/s.
