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 …

We have demonstrated simple reconfigurable all-optical logic operations based on four-
wave mixing in semiconductor optical amplifier and encoding information in the polarization …

We report the realization of a novel all-optical logic AND–NOR gate based on cross-gain
modulation (XGM). The used scheme requires only one SOA to perform the logic gate with …

The authors present a novel all-optical logic NOR gate using two-cascaded semiconductor
optical. amplifiers (SOAs) in a counterpropagating feedback configuration. This configuration …

All-optical xor operation has been demonstrated using a semiconductor optical amplifier
Mach-Zehnder interferometer (SOA-MZI) and delayed interferometer (DI) at 80 Gb/s. The DI …

Doppler reflectometry spatial and wavenumber resolution is analysed within the framework
of the linear Born approximation in the slab plasma model. An explicit expression for its …

As the speed of telecommunication systems increases and reaches the limit of electronic
devices, the demand for all-optical logic operations such as switching, decision-making …

All-optical OR operation has been demonstrated using a semiconductor optical amplifier
(SOA) and delayed interferometer (DI) at 20 and 40 Gb/s. The DI is based on a polarization …

Quantum-dot (QD) based semiconductor optical amplifiers (SOAs) are key components for a
large number of different applications in particular for all-optical communication networks …
