We deploy a supervised machine-learning model based on neural network to predict the temporal and spectral reshaping of simple sinusoidal modulation into pulse train having comb structure in frequency domain, which occurs upon nonlinear propagation an optical fibre. Both normal anomalous second-order dispersion regimes fibre are studied, speed is leveraged probe space input parameters for gener...

After conquering the core and metropolitan networks, fibre is now penetrating into the access domain. Its low loss and huge bandwidth enable the delivery of any present and foreseeable set of broadband services, and also make it a nice match to the wireless link to the end user. Cost effectiveness is a key issue, and will be decisive for the network topology choices. Point-to-point may be the m...

Quality of embedment of optical fibre sensors in carbon fibre-reinforced polymers plays an important role in the resultant properties of the composite, as well as for the correct monitoring of the structure. Therefore, availability of a tool able to check the optical fibre sensor-composite interaction becomes essential. High-resolution 3D X-ray Micro-Computed Tomography, or Micro-CT, is a relat...

Pervasive broadband access will transform cities to the net social, environmental and economic benefit of the e-City dweller as did the introduction of utility and transport network infrastructures. Yet without action, the quantity of greenhouse gas emissions attributable to the increasing energy consumption of access networks will become a serious threat to the environment. This paper introduc...

Optical fibre sensors, such as Fibre Bragg Gratings (FBGs), are growing in their utilisation, although very niche in their applications. To enable a more diverse range of end users, expensive application-specific optical fibre interrogation hardware needs to be made compatible with and, ideally, easily incorporated into existing instrumentation and measurement hardware. The Programmable Logic C...

With interest in the potential of optical fibres as the basis of next-generation thermoluminescence dosimeters (TLDs), the development of suitable forms of material and their fabrication has become a fast-growing endeavour. Present study focuses on three types of Ge-doped optical fibres with different structural arrangements and/or shapes, namely conventional cylindrical fibre, capillary fibre,...

Fibre Raman amplifiers are being deployed in many new long-haul and ultra long-haul fibre-optic transmission systems, making them the first and most widely commercialized nonlinear optical devices in telecommunications. One of the main reasons for this is their improved noise figure and reduced nonlinear penalty of fibre systems hence allowing for longer amplifier spans. In this paper, we have ...

We derive pulse propagation equation for a graphene-clad optical fibre, treating optical response of graphene and nonlinearity of the dielectric fibre core as perturbations in asymptotic expansion of Maxwell equations. We analyse the effective nonlinear and attenuation coefficients due to the graphene layer. Based on the recent experimental measurements of the nonlinear graphene conductivity, w...

Unlike conventional Polymer Optical Fibre (POF), single -mode Microstructured Polymer Optical Fibre (MPOF) can easily be fabricated, as required for many nonlinear applications. It was demonstrated that tungsten electrodes for poling and measuring the electro -optic coefficient could be incorporated in the PMMA fibre during the draw process. Lengths of up to 70m of this fibre were produced. For...

Propagation time through an optical fibre changes with the environment, e.g., a change in temperature alters the fibre length and its refractive index. These changes have negligible impact in many key fibre applications, e.g., telecommunications, however, they can be detrimental in many others. Examples are fibre-based interferometry (e.g., for precise measurement and sensing) and fibre-based t...
