“…Singh et al [6] have reported an all-optical half adder and half subtractor operating at 1 Gbps bit rate using continuouswave lasers as carrier sources and two semiconductor optical amplifiers as basic active elements. A novel scheme for concurrent implementation of all-optical half adder and AND & XOR logic gates based on nonlinear photonic crystal has been demonstrated by Ghadrdan [7]. Bakhtiar et al [8] have explained the functionality of an all-optical half subtractor based on nonlinear directional coupler using four waveguides and appropriately adjusting the refractive indices and selecting the proper length of the waveguides.…”

All-optical logic and arithmetic operations are expected to play an important role in high-speed communication systems. In this paper, we have presented a model to perform two basic arithmetic operations (addition/subtraction) on two binary digits based on a quantum dot semiconductor optical amplifier (QD-SOA)-assisted MachZehnder interferometer. Using two QD-SOA-based switches, we have designed a half adder/subtractor circuit. The main advantage of this circuit is that simultaneous addition and subtraction operations are realized at the outputs. This circuit is designed theoretically and verified through numerical simulations. The theoretical study is carried out by taking into account the effect of amplified spontaneous emission. The dependence of the peak data power and that of the QD-SOA current density and length on the ER and Q factor of the switching outcome are explored and assessed by means of numerical simulations. The desirable device parameters has been examined in order to obtain the optimum best performance.Keywords Quantum dot semiconductor optical amplifier · Mach-Zehnder interferometer · All-optical signal processing · All-optical arithmetic operation B Tanay Chattopadhyay

“…Similarly, two-dimensional (2D) and three-dimensional (3D) PCs are defined when the dielectric constant varies along two and three direction, respectively [1][2][3][4]. PBG property made these artificial structures suitable for designing different optical devices such as filters [5][6][7][8][9][10][11], demultiplexers [12][13][14][15][16][17] switches [18][19][20] and optical logics [18,[21][22][23][24][25][26][27][28]. The optical power splitter or divider is an indispensable component in photonic-integrated circuits which is used in fiber optic networks.…”

In this paper, an optical power divider with one input and four outputs has been proposed in a twodimensional photonic crystal with triangular lattice and simulated using dielectric holes in an air substrate. The dividing properties of the power divider have been numerically simulated and analyzed using the plane wave expansion and finite difference time domain methods. The results show that the transmittance of this divider can be as high as 94.22 % for λ = 1.55 µm; thus, the proposed structure is suitable for wavelength division multiplexing communication systems. Also, due to the small footprint of the proposed structure, this optical power divider is applicable for optical-integrated circuit design.

“…All the half adder include two output ports including one SUM port realized by logic gate XOR and CARRY port realized by logic gate AND to realize "add" operation, and the truth table for half adder is shown in Table 1. Presently, great efforts have been made on the all optical half adder and it was realized through cross structures [23] or nonlinear effects [24] in 2D PCs. Although the AND, NAND, XNOR, and NOR logic gate based on self collimated effect was realized in the report [16], the all optical half adder based on self-collimated effect has not yet been researched.…”
