“…105 A different approach to design AO-Toffoli and Fredkin gates utilized the frequency conversion properties of SOA. 106 An attempt to construct a modified Fredkin gate using SOA-MZI structure with the ability to perform 15 Boolean logic functions was proposed. However, the proposed work was a preliminary model that needed further improvements to bring down the BER value and increase the speed of operation.…”

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.

A characterization technique, including a mathematical model involving extensive computational resources, is introduced to study the behavior of an electro-optical space switch based on semiconductor optical amplifier (SOA). The model encompasses the precise emulation of device nonlinearities and its transient performance, allowing the characterization of its transient response. The calibration process includes the evaluation of parasites from the SOA connection, mounting and encapsulation, and parameter extraction of the active cavity. The numerical results are compared to experimental data for various operational conditions, with close similarities. The characterization technique can be adapted for other electro-optical devices, such as directedmodulated lasers, amplitude modulators and electro-optical switches.

“…So we exploited the attractive frequency encoding techniques for their advantageous aspects of unalternation of the signal even after reflection, refraction, and attenuation in long-haul communication networks 35 – 40 We use the optical signal of frequency “ν1” to encode the binary state “0” and frequency “ν2” to encode the binary state “1.” The basic block diagram of Toffoli gate is shown in Fig. 1, and the frequency-encoded data-based truth table of Toffoli logic gate is shown in Table 1.…”

Bit-error detection and correction is a very important part of a data communication network. In this article, we propose an optical approach to designing an error detection and correction circuit using Hamming code-based frequency encoded binary data and Toffoli gates.Here, the Toffoli gates are made of semiconductor optical amplifiers (SOAs) that work based on the nonlinear polarization rotation property. The characteristics of SOA, including very fast switching action (about 0.01 ns), low power consumption, frequency independent crosspolarization gain in the C-band, cascading property, etc., make the scheme attractive. The frequency encoded data-based proposed scheme will be effective for WDM communication networks. MATLAB simulation results testify to the feasibility of the proposed scheme.
