Journal ArticleDOI
Dimensioning of survivable WDM networks
TL;DR: Routing, planning of working capacity, rerouting, and planning of spare capacity in wavelength division multiplexing (WDM) networks are investigated and a complex cost model is presented.
Journal ArticleDOI
Architecture and design of optical channel protected ring networks
Peter Arijs,R Meersman,W. Van Parys,E. Iannone,A. Tanzi,M. Pierpaoli,F. Bentivoglio,Piet Demeester +7 more
TL;DR: In this paper, different optical ring architectures are considered and the optical add/drop multiplexer (OADM) functional architecture is described, and different aspects of ring network design and their impact on the network architecture are discussed.
Proceedings ArticleDOI
Reduction of wavelength blocking through partitioning with wavelength convertors
TL;DR: In this article, the authors conclude that the increased management complexity, if no wavelength translators are used, may be a stronger point to justify wavelength translation than the performance increase, which is relatively small.
Proceedings ArticleDOI
Quantifying the benefits of selective wavelength regeneration in ultra long-haul WDM networks
TL;DR: In this paper, the performance of transparent OXCs exploiting selective wavelength regeneration for different maximum transparency lengths was investigated and the tradeoff between increased transparency length and reduced cost assigned to O/E/O regeneration was revealed.
Journal ArticleDOI
Study of a Magnetooptic Contact for an Amplifying Waveguide Optical Isolator
W. Van Parys,Mathias Vanwolleghem,D. Van Thourhout,Roel Baets,Francois Lelarge,B. Thedrez,Lieven Lagae +6 more
TL;DR: In this paper, an ohmic metal-semiconductor contact was developed for an amplifying waveguide optical isolator. It is the result of magnetooptic waveguide simulations combined with experimental extraction of the contact resistivity, and the optimized contact scheme is a p++-doped hybrid In0.81Ga0.19As0.41P0.59-In 0.53Ga0.$ d47As structure.
