The elementary electronic‐logic‐gates, performing basic logic functions using electric
signals as input, act as a building block of modern digital circuits. Intriguingly, the …

In this paper, the implementation of an all-optical full adder based on a two-dimensional
photonic crystal is proposed. The proposed structure consists of hexagonal lattice of silicon …

Researchers have reported two-state quantum Hadamard gate using different optical
techniques. In this paper, authors propose a new concept for develo** the tristate form of …

The quantum optical tristate Pauli-X gate can broadly be used due to its very fast speed of
operation up to THz order, very fast information processing rate, and a wide domain of …

Quantum interference effects, namely Fano resonance producing asymmetric resonant
excitation and plasmon-induced transparency (PIT), are demonstrated in a plasmonic …

A phase shift gate deals with the change in phase of light signals passing through it. In this
paper, authors propose the tristate form of the phase shift gate and its implementation using …

Matrix-matrix multiplication has an important and essential role in digital data processing. In
optical parallel computation, many proposals using various matrix-matrix multiplication …

Arithmetic logic unit (ALU) is the most important unit in any computing system. Optical
computing is becoming popular day-by-day because of its ultrahigh processing speed and …

The advantages of multivalued logic in optical parallel computation need no introduction.
There are lots of proposals, already reported, where tristate, quarternary state logic …

Nonlinear optics has been of increased interest for all-optical signal, data and image
processing in high speed photonic networks. The application of multi-valued (nonbinary) …
