Optical computing and optical neural network have gained increasing attention in recent
years because of their potential advantages of parallel processing at the speed of light and …

Semiconductor optical amplifiers are useful building blocks for all-optical gates as
wavelength converters and OTDM demultiplexers. The paper reviews the progress from …

Communications can be broadly defined as the transfer of information from one point to
another. In optical fibre communications, this transfer is achieved by using light as the …

This invaluable book provides a comprehensive treatment of design and applications of
semiconductor optical amplifiers (SOA). SOA is an important component for optical …

All-optical logic gates (AO-LGs) are the key elements that play a pivotal role in the
development of future all-optical networks and all-optical computing. A complete overview of …

The paper reviews the current status and designs of all‐optical gates. Various schemes with
and without semiconductor optical amplifiers are discussed and compared. The optical …

All-optical XOR functionality has been demonstrated experimentally using an integrated
SOA-based Mach-Zehnder interferometer (SOA-MZI) at 20 and 40 Gb/s. The performance of …

We propose a new configuration of interference based OR, XOR, NOT and AND optical logic
gates on a two dimensional square lattice photonic crystal (PhC) platform. The working of …

A new design for concurrent implementation of all-optical half-adder and AND & XOR logic
gates based on nonlinear photonic crystal ring resonator has been proposed. The finite …

The results of optical logic exclusive-OR (XOR) at up to 20 Gbit/s in an integrated SOA-
based Mach-Zehnder interferometer are presented. For the first time, to the knowledge of the …
