“…The suggested all optical NOR gate has an improvement of 40% which makes it a practical design for photonic integrated circuits (PICs). Further, a rapid temporal response of 1.2 PS is achieved with a switching rate of 133GHz which is slower than those introduced in [10,11,19,20,21,22]. Finally, the suggested NOR gate can be used to boast the optical computing and signal processing.…”

He optical NOR gate is a key component of optical signal processing and network architecture. Optical NOR gates based on photonic crystal (PhC) architectures have recently been developed. The PhCs are optical periodic structures that can be used to regulate and manipulate the light flow [1]. For certain frequency ranges, light waves could not pass through the PhC, which is known as a forbidden bandgap. As a result, a flaw is inserted into the periodic structure to allow the forbidden frequencies to propagate.

“…Several approaches have been proposed up-to-date to demonstrate different optical logic operations and mostly are based on highly nonlinear optical fibers (HNLFs) or on nonlinear effects in semiconductors optical amplifiers (SOAs), integrated or not in interferometric structures [6][7][8][9][10][11]. SOA-based logic gates schemes although showing high potential for photonic integration present, however, speed limitation and latency, primarily due to the slowly recovery time of the SOAs.…”

In this paper, we demonstrate different optical logic gates using a single Mach-Zehnder interferometer with controlled phase modulators in each arm. The operational conditions to obtain 16 optical logic circuits, using the same design, are investigated and are a result of a constructive or destructive interference process. The proposed configuration presents significant low complexity and high scalability, and its feasibility is evaluated through numerical simulations.

“…Some phase‐encoded logic operations mainly XOR and XNOR have been proposed using phase information processing of FWM in SOA, high nonlinearity fiber (HNLF) and periodically poled lithium niobate (PPLN) [17–23]. Reconfigurable logic unit with phase‐encoded data has been proposed using multimode interference waveguide in photonic crystal and cross‐gain modulation (XGM) in SOA with multi‐inputs [24, 25]. However, multimode interference waveguide in photonic crystal has some limitation because of its comparatively large size and in case of XGM, it has lower speed than intraband FWM in SOA supported only on carrier heating and spectral hole burning mechanism.…”
