All optical XOR logic gates: technologies and experiment demonstrations

Abstract: This article reviews the current status and technologies of all-optical XOR gates. Various schemes with semiconductor optical amplifiers, particularly those associated with interferometric structures, are discussed and compared. Finally, the applications of all-optical XOR gates to emerging networks are explored, and the future direction is outlined.

Performance analysis of the all-optical XOR gate using SOA-MZI with a differential modulation scheme

Abstract: In this paper, the all-optical exclusive OR gate using an integrated SOA-based Mach–Zehnder interferometer with a differential modulation scheme is proved to exceed the operation speed limit effectively through numerical analysis for the first time. The control-signal pulse parameters and delay time are discussed and designed to optimize the performance of the XOR gate. © 2004 Wiley Periodicals, Inc.

Evolution of multiprotocol label switching

Abstract: Multiprotocol label switching (MPLS) is rapidly emerging as an Internet Engineering Task Force (IETF) standard intended to enhance the speed, scalability, and service provisioning capabilities in the Internet. MPLS uses the technique of packet forwarding based on labels, to enable the implementation of a simpler high-performance packet forwarding engine. This also decouples packet forwarding from routing, facilitating the provision of varied routing services independent of the packet forwarding paradigm. The authors track the evolution of this technology in relation to other existing technologies. Then an overview of the MPLS architecture and design is provided. In addition, some of the work that was a precursor to MPLS is discussed, as well as related issues and debates.

Mach–Zehnder interferometer-based all-optical reversible logic gate

Abstract: In recent years, reversible logic has emerged as a promising computing paradigm having application in low-power CMOS, quantum computing, nanotechnology and optical computing. Optical logic gates have the potential to work at macroscopic (light pulses carry information), or quantum (single photons carry information) levels with great efficiency. However, relatively little has been published on designing reversible logic circuits in all-optical domain. In this paper, we propose and design a novel scheme of Toffoli and Feynman gates in all-optical domain. We have described their principle of operations and used a theoretical model to assist this task, finally confirming through numerical simulations. Semiconductor optical amplifier (SOA)-based Mach–Zehnder interferometer (MZI) can play a significant role in this field of ultra-fast all-optical signal processing. The all-optical reversible circuits presented in this paper will be useful to perform different arithmetic (full adder, BCD adder) and logical (realization of Boolean function) operations in the domain of reversible logic-based information processing.

Tb/s Optical Logic Gates Based on Quantum-Dot Semiconductor Optical Amplifiers

Abstract: The performance of an ultrafast all-optical logic gate based on quantum-dot semiconductor optical amplifier (QD-SOA) has been theoretically analyzed in this paper. We introduce a novel approach to accelerate the gain recovery process with a control pulse (CP) using the cross-gain modulation (XGM) effect. It is shown that the optical XOR gate in a Mach-Zehnder interferometer-based structure is feasible at Tb/s speeds with proper quality factor. The operation capability at 2.5 Tb/s with a Q-factor of 4.9 and 2 Tb/s with a Q -factor of 8.8 is reported for the first time. This capability indicates great potential for ultrafast all-optical signal processing and switching.
