Recent advances in optical communications not only increase the capacities of
communication system but also improve the system dynamicity and survivability. Various …

The book gives an in-depth description of key devices of current and next generation fibre
optic communication networks. Devices treated include semiconductor lasers, optical …

The paper considers optical node architectures for elastic optical networks. They use
switching fabric topologies which are similar to the three-stage Clos switching networks …

In this work, a detailed performance analysis for a Mach–Zehnder interferometer (MZI)
optical switch with a channel profile of titanium-indiffused lithium niobate (Ti: LiNbO3) is …

Abstract This article reviews Mach–Zehnder interferometer waveguiding structure-based
optical switches in terms of their working principle, design, fabrication, and related …

We present a novel setup that allows the observation of the geometric phase that
accompanies polarization changes in monochromatic light beams for which the initial and …

In this paper, we address the problem of the strict-sense nonblocking operation of an elastic
optical switch. Elastic optical switches are used as nodes in elastic optical networks (EONs) …

Performance improvement of a broadcast-and-select (B&S) optical switch based on an
electro-absorption modulator (EAM)-gate array is presented. The introduction of a novel spot …

This paper reviews the basic of multimode interference (MMI) coupler and its application in
optics, especially for optical switching. We have demonstrated the design & performance of …

Optical switching is driven by need to offer more flexibility, better security and efficient
utilization of optical network. Switching operation in lithium niobate based on electro-optic …
