SOA Based Photonic Integrated WDM Cross-Connects for Optical Metro-Access Networks
Applied Sciences, 2017 We present a novel optical metro node architecture that exploits the Wavelength Division Multiplexing (WDM) optical cross-connect nodes for interconnecting network elements, as well as computing and storage resources.

Performance of WDM transport networks [PDF]
IEEE Journal on Selected Areas in Communications, 1998 Wavelength division multiplexed point-to-point transport is becoming commonplace in wide area networks. With the expectation that the next step is end-to-end networking of wavelengths (in the optical domain without conversion to electronics), there is a need for new design techniques, a new understanding of the performance issues, and a new performance

Migrating from static to dynamic survivable WDM networks: the capacity-availability trade-off
Revista Facultad de Ingeniería Universidad de Antioquia, 2012 The benefit of migrating from fault-tolerant static WDM networks to survivable dynamic WDM networks is evaluated in terms of the trade-off between the additional network capacity (number of wavelengths) required to provide fault tolerance capability and

International Journal for Numerical Methods in Fluids, EarlyView.This article provides important geometric formulas for node‐centered, edge‐based schemes in any number of dimensions. These formulas are noteworthy, as they do not require the explicit formation of dual regions. We prove several key geometric results, with a particular focus on the four‐dimensional case, due to potential space‐time applications ...

Broadband Parametric Amplification in AlGaAs‐on‐Insulator Nanowaveguides
Laser &Photonics Reviews, EarlyView.Harnessing the exceptional nonlinearity of AlGaAs‐on‐insulator nanowaveguides, four‐wave‐mixing parametric amplification achieves a record net on‐chip gain of 56 dB and a gain bandwidth exceeding 415 nm at telecom wavelengths. These results establish AlGaAsOI as a powerful platform for compact, high‐performance integrated nonlinear optical ...

The wavelength conversion in WDM networks [PDF]
Communications - Scientific letters of the University of Zilina, 2004 In this article we deal with a problem of wavelength conversion in WDM networks and with the wavelength conversion impact on throughput of network. The throughput of networks is determined in terms of blocking probability. The optical networks can be built without wavelength conversion or with full or limited wavelength conversion.

Laser &Photonics Reviews, EarlyView.ABSTRACT The growing demands of artificial intelligence require new energy‐efficient and nonvolatile computing paradigms. To meet this challenge, we demonstrate a foundational device platform for optical fiber computing that targets the signal decay and power consumption bottlenecks of conventional systems.
