In this paper, XOR gate is implemented based on nonlinear polarization rotation, initiated by Kerr effect in a single highly nonlinear fiber (HNLF) having length of 5km and bit rate of 20Gbps. Two cross-polarize
The basic working principle of MZI is discussed in Section 2. Analytical description of XOR, XNOR, and AND logic gates is given and their simulation results obtained from MATLAB can be found in Section 3. The results obtained through OptiBPM and their discussions are given in Section 4, and...
Implement a 2:4 decoder with AND and NOT gates. Solution Figure 2.64 shows an implementation for the 2:4 decoder, using four AND gates. Each gate depends on either the true or the complementary form of each input. In general, an N:2N decoder can be constructed from 2N N-input AND gat...
Presently, the densest cell-based GaAs gate arrays offer up to 200K raw gates, while CMOS arrays can integrate up to 800K raw gates. It is worth noting that the density of GaAs DCFL is currently increasing more rapidly than the density of silicon CMOS. GaAs competes favorably with ECL in...
The S‐box is implemented with lookup table as a 16 � 16 array, as shown in Figure 5, and the output of the S‐boxes is combined into one 32‐bit word and is the input of the linear transform, which applies the cyclic left‐shift and XOR operation [14]. Because of the ...

Quantum gates have been proposed using the coupled resonator optical waveguides (CROWs), to implement single qubit gates and gates using two qubits [31]. Also, research work on the reversible optical XOR and XNOR gates using the resonator structure consisting of linear as well as nonlinear rods ...
The real-time implementation of the randomizer can be done by using the logic diagram depicted in Fig. 4. As an alternative, we note that, since the LFSR is always preset to the all-one state at the beginning of a new block, the sequence generated by the randomizer is always the same...
