“…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.

“…In recent years, people have demonstrated optical logic using different schemes, including using dual semiconductor optical amplifier (SOA) Mach-Zehnder interferometer(MZI) [2,3], semiconductor laser amplifier (SLA) loop mirror [4], ultrafast nonlinear interferometer (UNI) [5], four-wave mixing (FWM) in SOA [6] and cross gain (XPM)/cross phase (XPM) modulation in nonlinear devices [7]. Among above schemes, the SOA based MZI has the advantage of being relatively stable, simple and compact.…”

Abstract:The scheme to realize high speed (~250Gb/s) all-optical Boolean logic gates using semiconductor optica amplifiers with quantum-dot (QD-SOA) is introduced and analyzed in this review. Numerical simulation method was presented by solving the rate equation and taking into account nonlinear dynamics including carrier heating and spectral hole-burning. Binary phase shift keyed (BPSK) signal and on-off keyed signal are used to generate high speed all-optical logic gates. The applications based on all-optical logic gates such as, all-optical latches, pseudo random bit sequence (PRBS) generation and all-optical encryption, are also discussed in this review. Results show that the scheme based on QD-SOA is a promising method for the realization of high speed all-optical communication system in the future.

“…The all-optical XOR gates may be classified into two types, depending on the methodology used to achieve the nonlinear operation of the logic devices: (i) fiber nonlinearity-based logic gates [2] and (ii) semiconductor optical amplifier (SOA)-based logic gates [3][4][5][6][7][8][9]. Logic gates using the integrated SOA-based Mach-Zehnder interferometer (SOA-MZI) [8,9] are attractive due to their simple structure, stable and efficient operation, cascading capability, and easy implementation as compared with fiber-based logic gates.…”
