Development of 1GHz Clocked Entangled LEDs for Fibre Networks
… of which are essential for realising quantum networks. To be compatible with real-world applications, such a source must further conform to basic requirements including operation at telecom wavelengths and high clock rates. Today, most quantum dot experiments are carried out with sophisticated …

The mechanical and magnetic behaviour of sintered fibre networks and their suitability for a therapeutic, biomedical application
**Background:** Sintered, metallic fibre networks have been used in the design of a range of technical devices in the past years (e.g. heat exchangers or catalysts). One potential application in the field of therapeutic, biomedical engineering is the magnetic-mechanical stimulation of bone growth …

An Approach to Optimising the Design of a Repeaterless Global Quantum Network
… investigations on its design are limited. Fibre-based optimisations focus on device placement. Cost analysis including nodes, fibres and usage of optical switching has been insufficiently explored. Satellite quantum key distribution is important for global reach. Research focuses mainly on …

A Quantum Technique for Monitoring Physical Layer Security of Optical Communication
Optical fibre networks are advancing rapidly to meet growing traffic demands. Security issues, including attack management, have become increasingly important for optical communication networks owing to the vulnerabilities associated with tapping light from optical fibre link. Physical layer …

Survivability and resilience mechanisms in modern optical fibre systems
Optical fibre networks play an increasingly prominent role in communications. As networks grow in size and complexity, the probability and impact of failures increase. In this dissertation, different optical network concepts, survivability and resilience methods are considered. Link and Path …

Mechanics of biomimetic materials for tissue engineering of the intervertebral disc
… then demonstrated that materials mimicking the fibre-reinforced nature of natural tissues can be developed by infiltrating thick electrospun fibre networks with alginate. These fibre-reinforced hydrogels have tensile and compressive properties that can be separately altered. To better understand …

Semicarbazide organogels containing inorganic nanoparticles : new supramer particle hybrid systems
… into supramolecular structures with fibre-like architecture. Small amounts of semicarbazide gelator in an organic liquid are sufficient to cause gelation of organic solvents. These compounds have been equipped with various functionalities. Due to the functionalisation, the outer …

The vibro-acoustic modelling and analysis of damage mechanisms in paper
… of paper consists of a random mesh of paper fibres connected by hydrogen bonds. This implies the existence of the two damage mechanisms of interest, the failure of a fibre/fibre bond and the failure of a fibre. The majority of this work focuses on the development of a novel hybrid …

Practical, High-Speed, Gaussian Modulated Coherent State Continuous Variable Quantum Key Distribution with Real-Time Post Processing
… compatibility with classical coherent optical fibre networks. For successful system deployment, it is essential to implement practical, high-speed, systems that distils secret keys in real-time. Most existing demonstrations of continuous variable key distribution systems utilise bulky …

GaAs-based quantum well and quantum dot light-emitting diodes and lasers for 1.3 and 1.55 um emission
… pushes the band¬width requirements for fibre networks at an unprecedented pace. Optical fibres have largely replaced copper wire in communications and have developed from a curiosity status to be¬ing the dominant technology. The goal of this thesis is the research of new materials for …
