We present a review of the integer linear programming (ILP) formulations that have been
proposed for the routing and wavelength assignment problem in WDM optical networks …

For a fast rotating condensate in a harmonic trap, we investigate the structure of the vortex
lattice using wave functions minimizing the Gross-Pitaevskii energy in the lowest Landau …

As elastic optical networks (EONs) are expected to convey high bitrate connections, a failure
in these networks causes vast data losses. Thus, addressing the problem of survivability in …

Physical impairments in optical fiber transmission necessitate the use of regeneration at
certain intermediate nodes, at least for certain lengthy lightpaths. We design and implement …

In translucent optical networks, the physical layer impairments degrading the optical signal
are considered in the network planning. In this paper, we investigate the offline problem of …

Abstract Elastic Optical Networks (EONs) were introduced to eliminate the challenges of
Wavelength Division Multiplexing (WDM) networks. EONs can improve resource efficiency …

In translucent (or managed reach) WDM optical networks, regenerators are employed at
specific nodes. Some of the connections in such networks are routed transparently, while …

In this paper, we propose two strategies for sparse regenerator placement (RP) in
translucent optical networks, named most used regenerator placement (MU-RP), and most …

The transmission capacity of traditional single core fibers is reaching its upper bound. Space-
division multiplexing (SDM) leveraging multi-core fibers is considered to be a promising …

In an all-optical WDM network; optical fibers are used to transmit data followed by WDM
technology. An optical fiber carries light along its length path at high rates and with little loss …
