The wave function of a composite system is defined in relativity on a space–time surface. In
the explicitly covariant light-front dynamics, reviewed in the present article, the wave …

In WDM optical networks, the physical layer impairments (PLIs) and their significance
depend on network type-opaque, translucent, or transparent; the reach-access, metro, or …

The state of the art of modern lightwave system design Recent advances in lightwave
technology have led to an explosion of high-speed global information systems throughout …

Optical networks are moving from opaque and translucent architectures towards all-optical
(transparent) architectures. In translucent architectures a small amount of regeneration (eg …

In this paper we study an alternate network architecture, called translucent network, to the
fully transparent and fully opaque network architectures. In a translucent wavelength-routed …

The transmission reach of signals in optical transmission systems is limited. To go beyond
these transparent reach limits, signal regeneration is necessary to re-amplify, reshape, and …

Transport networks evolved from DCS (Digital Cross-connect Systems)-based mesh
architectures, to SONET/SDH (Synchronous Optical Networking/Synchronous Digital …

Multi-band optical fiber transmission is generally proposed for capacity upgrades in optical
transport networks. To comprehensively assess the potential of multi-band transmission, key …

This paper addresses the problem of survivable lightpath provisioning in wavelength-
division-multiplexing (WDM) mesh networks, taking into consideration optical-layer …

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 …
