“…All-optical logic gates, which can fulfill various logical functions operations and capable of performing complex light control in all-optical circuits, have received much attention for their potential application in ultrafast information processing and optical computing systems. Various PhC structures have already been proposed to realize all-optical logic gates [4][5][6][7][8][9][10]. The most PhC-based logic gates rely either on resonator cavities with finite filling time or branching structures with a very confined interaction volume that is both highly sensitive to production variations and in need of pre-defines input signal phases.…”

In this manuscript we propose an easily scalable true all-optical AND logic gate for pulsed signal operation based on band-gap transmission within nonlinear realistic air-hole type coupled photonic crystal waveguides (C-PCW). We call it "true" all-optical AND logic gate, because all AND gate topologies operate with temporal solitons that maintain a stable pulse envelope during the optical signal processing along the different C-PCW modules yielding ultrafast full-optical digital signal processing. We directly use the registered (output) signal pulse as new input signal between multiple concatenated nonlinear C-PCW modules (i.e. AND gates) to setup a multiple-input true all-optical AND logic gate. Extensive full-wave computational electromagnetic analysis proves the correctness of our theoretical studies and the proposed operation principle of the multiple-input AND logic gate is vividly demonstrated for realistic C-PCWs.

“…But, a few reported works suffer from some fundamental limitations such as big size, low bandwidth and high loss. Besides, there are many reported works that are based on photonic crystals with advantage of compactness [5][6]. Unfortunately, its downsides are high loss and difficult integration with Si-based optical devices.…”

In this paper, an all-optical logic gate based on 2x2 (MMI) multimode interference coupler is theoretically designed and simulated using three-dimensional beam propagation method (3D-BPM) and effective index method (EIM) to analyze and evaluate the performance of the device. The proposed device is used to convert phase information of input optical signals to amplitude at the output ports of MMI. With this mechanism, the device can operates as a logical half adder. Simulation results show that the optical half adder archives with insertion loss and extinction ratio from ON to OFF logiclevel below 0.7 dB and over 40 dB, respectively. Furthermore, wide bandwidth of 100 nm is also an advantage of this devices. Therefore, it can be applied to all optical signal processing in next generation optical networks as well as in photonic integrated circuits.Index Terms-Multimode interference, all-optical logic gates, logical half adder. !

“…The performance of SOA-MZI-based XOR gate have been analyzed through numerical simulations, to generalize the optimal parameters as well as the suitable operating conditions [9][10][11][12][13][14]. Ishizaka et al [15] proposed a novel ultra-compact all-optical XOR and AND logic gates without using nonlinear optics. MZI is widely used to generate the logical functions (AND, XOR, XNOR), multiplexer, encoder, flip-flop, and adder/subtractor along with semiconductor optical amplifier (SOA) [16][17][18][19][20].…”
