optical networks working on WDM (Wavelength Division Multiplexing) are prone to component failures. As these networks carry huge amount of information, fault management has become vital in maintaining survivability of high speed optical networks. In WDM networks failure of networks, failure of network element may cause the failure of several optical channels, thereby leading to large data losse...

Measuring fine track widths with optical instruments has become increasingly difficult as the dimensions of the features of interest have become smaller than the traditional optical resolution limit. This has caused a move to non-optical methods such as scanning electron and atomic force microscopy techniques, or novel optical methods combined with signal processing techniques to provide measur...

Optical communication systems and networks will continue to play a significant role in the development and deployment of emerging network infrastructures. These networks are expected to support the diverse requirements of a broad range of existing and future applications. To accommodate this wide spectrum of applications, network infrastructures are evolving rapidly in terms of technology and a...

optical coherence tomography (oct) uses the spatial and temporal coherence properties of optical waves backscattered from a tissue sample to form an image. an inherent characteristic of coherent imaging is the presence of speckle noise. in this study we use a new ensemble framework which is a combination of several multi-layer perceptron (mlp) neural networks to denoise oct images. the noise is...

This article considers, for the first time, optical performance monitoring (OPM) in few mode fiber (FMF)-based networks. 1-D features vector, extracted by projecting a 2-D asynchronous in-phase quadrature histogram (IQH), and 2D IQH are proposed to achieve OPM FMF-based network. Three machine learning algorithms employed their performances compared. These include support vector machine, random ...
