چکیده
In this paper, a new scheme is proposed to realize reconfigurable and multifunction optical logic gates (XOR, XNOR, NAND, OR) using Mach–Zehnder interferometer with tunable thermo-optic phase shifter (TOPS). The are realized by tuning the of an signal TOPS without changing physical device structure. logical input “0” or “1” considered corresponding at TOPS. output depends on light intensity ports. designed silicon insulator (SOI) platform simulation result shows that on–off extinction ratio greater than 37 dB 1550 nm >25 for C-band. Moreover, it has low insertion loss 0.09 wavelength <0.8 C-band window. can be promising programmable photonic integrated circuits.

A Design Methodology for Reliable MRF-Based Logic Gates
Probabilistic-based methods have been used for designing noise tolerant circuits recently. In these methods, however, there is not any reliability mechanism that is essential for nanometer digital VLSI circuits. In this paper, we propose a novel method for designing reliable probabilistic-based logic gates. The advantage of the proposed method in comparison with previous probabilistic-based met...
متن کاملA rule-based evaluation of ladder logic diagram and timed petri nets for programmable logic controllers
This paper describes an evaluation through a case study by measuring a rule-based approach, which proposed for ladder logic diagrams and Petri nets. In the beginning, programmable logic controllers were widely designed by ladder logic diagrams. When complexity and functionality of manufacturing systems increases, developing their software is becoming more difficult. Thus, Petri nets as a high l...
متن کامل40 Gb/s reconfigurable optical logic gates based on FWM in silicon waveguide.
Here we experimentally demonstrate reconfigurable logic gates via four-wave-mixing (FWM) in silicon waveguide with an operating speed of up to 40 Gb/s. After demodulated by a 40-GHz delay interferometer (DI), four non-return-to-zero differential phase shift keying (NRZ-DPSK) signals with carefully selected wavelengths are launched into the waveguide at the same time. Thanks to the effective FWM...
متن کاملReconfigurable optical directed-logic circuits using microresonator-based optical switches.
We present a reconfigurable optical directed logic architecture that offers several significant improvements over the original directed logic presented by Hardy and Shamir. Specific embodiments of on-chip, waveguided, large-scale-integrated, cellular optical directed logic fabrics are proposed and analyzed. Five important logic functions are presented as examples to show that the same switch fa...
متن کاملA Bipartitioning Algorithm for Dynamic Reconfigurable Programmable Logic
Most partitioning algorithms have been developed for conventional programmable logic (especially FPGAs), being their main goal the minimisation of the signals constituting the interface (cutsize) between partitions, while balancing partition sizes. New families of dynamic reconfigurable programmable logic (DRPL) offer new possibilities to improve functional density of circuits, but traditional ...
