“…Up to now, many schemes have been demonstrated to realize various elementary optical logic operations, including AND, OR, NOT, XOR, XNOR, NAND, and NOR [32,55,61,62,[76][77][78][79][80][81][82][83][84][85]. By combining multiple elementary optical logic operations, advanced logic operations such as half-adder, half-subtractor, full-adder, and full-subtractor have also been proposed and demonstrated [36,[86][87][88][89][90][91].…”

The era of cloud computing has fuelled the increasing demand on data centers for highperformance, high-speed data storage and computing. Digital signal processing may find applications in future cloud computing networks containing a large sum of data centers. Addition and subtraction are considered to be fundamental building blocks of digital signal processing which are ubiquitous in microprocessors for arithmetic operations. However, the processing speed is limited by the electronic bottleneck. It might be valuable to implement high-speed arithmetic operations of addition and subtraction in the optical domain. In this chapter, recent results of M-ary optical arithmetic operations for high base numbers are presented. By exploiting degenerate and nondegenerate four-wave mixing (FWM) in highly nonlinear fibers (HNLFs), graphene-assisted optical devices, and silicon waveguide devices, various types of two-/three-input high-speed quaternary/octal/decimal/hexadecimal optical computing operations have been demonstrated. Operation speed up to 50 Gbaud of this computing approach is experimentally examined. The demonstrated M-ary optical computing using high base numbers may facilitate advanced data management and superior network performance.

“…Clearly, the gates should operate at high bit rate to be competitive to their electronic counterparts. High-speed XOR gates based on loop and UNI configurations are reported in [86] and [87], while integrated versions based on XPM gates are reported in [88] and [89]. The function of the XPM gate used as an XOR gate is shown schematically in Fig.…”

Abstract-Semiconductor optical amplifiers are useful building blocks for all-optical gates as wavelength converters and OTDM demultiplexers. This paper reviews the progress from simple gates using cross-gain modulation and four-wave mixing to the integrated interferometric gates using cross-phase modulation. These gates are very efficient for high-speed signal processing and will open up interesting new areas, such as all-optical regeneration and high-speed all-optical logic functions.Index Terms-Add/drop multiplexer, optical gate, optical processing, semiconductor optical amplifier, wavelength converter.

“…The capability of the interferometric wavelength converter as an XOR gate has previously been demonstrated at up to 20 Gb/s in [5], where a Mach-Zehnder interferometer (MZI) was employed. Furthermore, standard 40-Gb/s wavelength conversion has been performed in a Michelson interferometer [6], indicating the high-speed potential of the IWC.…”
