The feasibility of implementing all-optical circular shift register is theoretically investigated and described using Silicon waveguide based micro-ring resonator (MRR) as nonlinear all-optical switch, which can be used as a building block for optical signal processing networks. The schemes of left and right circular shifting registers are proposed. The performance of the circuit is evaluated through...
A method for high-speed all optical Manchester encoded signal generation is proposed using micro-ring resonator. In the present paper the advantages of ring resonator based switch have been exploited to design an integrated all-optical Manchester encoder circuit. The performance of the circuit is evaluated through numerical simulation, which confirms its feasibility in terms of the choice of the critical...
Optical phase conjugation (OPC) is one of the important properties in optical nonlinear material. In this manuscript we have tried to explain the OPC characteristics of a gold nanoparticle doped-alumina (Au:Al2O3) theoretically. Numerical simulation is also given to explain the switching characteristics. We also propose 2D matrix switching using this nonlinear material.
Recently design of reversible logic circuits draw much attention in nanotechnology and quantum computing. Conventional logic circuits are not reversible. A reversible circuit maps each input vector, into a unique output vector and vice versa. In this paper, we propose a novel scheme of Toffoli and Feynman gates in all-optical domain using terahertz optical asymmetric demultiplexer (TOAD). Both the...
In electronic computing systems, the binary-coded decimal (BCD) method encodes decimal numbers with each digit represented by its own four-bit binary sequence. The method allows easy conversion to decimal digits for printing or display and also offers rapid decimal calculations. A proposed all-optical BCD adder uses a terahertz optical asymmetric demultiplexer (TOAD) to perform BCD addition in all-optical...
