The present document is devoted to the question of whether effective computation can be performed by the interaction of solitons [24, 34] in a bulk medium. The resulting computational system would fulfill the promise of Toffoli’s “programmable matter” [42] — offering computation that is very close to the underlying physics, and therefore potentially providing ultra-scale parallel processing. Th...

Reversible logic gates are very much in demand for the future computing technologies as they are known to produce zero power dissipation under ideal conditions. The applications of reversible logic gates include ultralow power, nano computing, quantum computing, low power CMOS design, optical information processing, bioinformatics etc. This paper proposes an improved design of a multiplier usin...

In this paper, a novel design of an all-optical half-adder (HA) based on two two-ring resonators in two-dimensional square-lattice photonic crystal (PC) structure without nonlinear materials is proposed. The HA comprises AND and XOR gates where each gate composed cross-shaped waveguides 2D PC that are filled with silicon (Si) rods silica (SiO2). analyzed simulated using plane-wave expansion (PW...

A deflection routing algorithm that can be applied to a novel self-routing address scheme for networks with arbitrary topology is proposed. The proposed deflection routing algorithm can be implemented all-optically using bitwise optical logic gates. Besides the primary output link selection, alternate output link choices by a packet at each node in case of deflection are also encoded in the add...

We propose a most economical design of the Optical Shared MemOry Supercomputer Interconnect System (OSMOSIS) all-optical, wavelength-space crossbar switch fabric. It is shown, by analysis and simulation, that the total number of on-off gates required for the proposed N × N switch fabric can scale asymptotically as N ln N if the number of input/output ports N can be factored into a product of sm...

All-optical logic circuits based on the polarization properties of nondegenerate four-wave mixing are proposed. Schemes to perform multiple triple-product logic functions are discussed, and it is shown that higher-level Boolean operations that involve several bits can be implemented without resorting to the standard two-input gates. As a simple illustration of the idea, a circuit that performs ...

Quantum Logic Processors can be implemented with Mach Zehnder Interferometer(MZI) configurations for the Quantum logic operations and gates. In this paper, its implementation for both optical and electronic system has been presented. The correspondence between Jones matrices for photon polarizations and Pauli spin matrices for electrons gives a representation of all the unitary matrices for the...

By exploiting the polarization multistability of polaritons, we show that polarized signals can be conducted in the plane of a semiconductor microcavity along controlled channels or "neurons." Furthermore, because of the interaction of polaritons with opposite spins it is possible to realize binary logic gates operating on the polarization degree of freedom. Multiple gates can be integrated tog...

In future high-speed self-routing photonic networks based on all-optical time division multiplexing (OTDM) it is highly desirable to carry out packet switching, clock recovery and demultplexing in the optical domain in order to avoid the bottleneck due to the optoelectronics conversion. In this paper we propose a self-routing OTDM node structure composed of an all-optical router and demultiplex...

We present the procedure for designing a high speed and low power all-optical analog to digital converter (AO-ADC), by integrating InGaAsP semiconductor optical amplifier (SOA) with InP based photonic crystal (PhC) drop filters. The self-phase modulation in the SOA can shift the frequency of the Gaussian input pulse. The two output PhC based drop filters are designed to appropriately code the f...
