Повний текст джерелаTransport of information through a multimode optical fibre raises challenges when one wants to increase the data traffic using many spatial modes due to modal cross-talk and dispersion. Instead of considering those complex mixing of modes as a detrimental process, in this dissertation, we harness its mode mixing to process quantum optical information. We implement a reconfigurable linear optical network, a fundamental building block for scalable quantum technologies, based on an inverse photonic approach exploiting the technology of wavefront shaping. We experimentally demonstrate manipulation of two-photon quantum interference on various linear optical networks across both spatial and polarization degrees of freedom. In particular, we experimentally show the zero-transmission law in Fourier and Sylvester interferometers, which are used to certificate the degree of indistinguishability of an input state. Moreover, thanks to the ability to implement a non-unitary network, we observe the photon anti-coalescence effect in all output configurations, as well as the realization of a tunable coherent absorption experiment. Therefore, we demonstrate the reconfigurability, accuracy, scalability and robustness of the implemented linear optical networks for quantum information processing. Furthermore, we study the statistical properties of one-and two-photon speckles generated from various ground-truth states of light after propagating through a multimode fibre. These statistical properties of speckles can be used to extract information about the dimensionality, purity, and indistinguishability of an unknown input state of light, therefore allowing for state classification. Our results highlight the potential of complex media combined with wavefront shaping for quantum information processing

Повний текст джерелаModern graphics processing units, GPUs, have evolved into high-performance processors with programmable vertex and pixel shaders. With these new abilities a new subfield of research, dubbed GPGPU for General Purpose computing on the GPU has emerged, in areas as oil exploration, processing of sound effects, neural networks, cryptography and image processing. As the GPUs functionality and performance are still increasing, more programmers are appealed by their computational power. To understand the performance of paper materials a detailed characterisation of the fibre cross-sections is necessary. Using scanning electron microscopy, SEM, fibres embedded in epoxy are depicted. These images have to be analysed and quantified. In this master thesis we explore the possibility of taking advantage of todays generation of GPUs performance when analysing digital images of fibre cross-sections. We implemented common algorithms such as the median filter, the SUSAN smoothing filter and various mathematical morphology operations using the high-level shader language OpenGL Shader Language, GLSL. When measured against equivalent image processing opreations run on the CPU, we have found our GPU solution to perform about the same. The operations run much faster on the GPU, but due to overhead of binding FBOs, intialising shader programs and transfering data between the CPU and the GPU, the end result is about the same on the GPU and CPU implementations. We have deliberatly worked with commodity hardware to see what one can gain with just replacing the graphics card in the engineer's PCs. With newer hardware the results would tilt heavily towards the GPU implementations. We have concluded that making a paper fibre cross-section analysis program based on GPU image processing with commodity hardware is indeed feasible, and would give some benefits to the user interactivity. But it is also harder to implement because the field is still young, with immature compilers and debugging tools and few solid libraries.

Interfaces fibra-matriz tem um papel muito importante no desempenho de compósitos de matriz cerâmica. Sendo a interação entre fibra e matriz for muito forte, o compósito se comportará como uma cerâmica monolítica, e sendo muito fraca, o compósito perderá sua integridade estrutural e suas propriedades interlaminares. Zircônia monoclínica (não-estabilizada) tem mostrado ser uma boa alternativa na produção de interfaces fibra-matriz para compósitos cerâmicos à base de alumina devido à sua baixa interação química durante a sinterização e também devido ao fenômeno de microtrincamento causado pela transformação tetragonal-monoclínica durante o resfriamento. Interfaces porosas à base de zircônia monoclínica, as quais apresentam baixa tenacidade devido à sua porosidade e microtrincamento, haviam sido usadas no passado para criar interfaces com baixa interação entre fibras de safira e matrizes de alumina. Neste sistema, as interfaces se mostraram quimicamente estáveis mesmo acima de 1300 °C. Compósitos tenazes à base de alumina haviam sido fabricados com zircônia monoclínica como interface. Entretanto, a porosidade da matriz era ? 13%, o que dificulta a interpretação dos resultados, pois as propriedades mecânicas do compósito não podem ser claramente atribuídas às propriedades da zircônia monoclínica. Neste trabalho, compósitos-modelo com matriz densa e fibras individuais de alumina foram produzidos. A interface fibra-matriz foi produzida através de recobrimento por dip-coating das fibras em suspensões cerâmicas de zircônia monoclínica. Diferentes tamanhos de partícula foram utilizados no processo de dip-coating com o objetivo de variar a porosidade e assim, as propriedades das interfaces. A tensão de cisalhamento interfacial foi determinada através do teste de pushin nas fibras. O fenômeno de deflexão de trincas foi avaliado através de trincas criadas por indentação Vickers e o fenômeno de pullout das fibras através de observações nas superfícies de fratura. Propriedades como tenacidade à fratura, dureza e módulo de elasticidade da matriz e interface foram avaliadas para determinar os parâmetros de deflexão de trincas propostos por He e Hutchinson.
Abstract : Fibre-matrix interface properties play an important role on the performance of ceramic matrix composites. Being the fibre-matrix interaction too strong, the composite will behave such as a monolithic ceramic and being too weak, the composite will lose its structural integrity and its interlaminar properties. Monoclinic (unstabilized) zirconia has shown to be a suitable alternative for the production of fibre-matrix interfaces for alumina ceramic matrix composites due to its low chemical interaction during sintering and due to the microcracking phenomenon caused by the tetragonal-monoclinic transformation during cooling. Porous oxide coatings of monoclinic zirconia, which have low toughness because of their porosity and microcracking, have been used in the past to achieve debonding between sapphire fibres and alumina matrices and were to be chemically stable with sapphire above 1300 °C. Tough alumina matrix composites have been fabricated using monoclinic zirconia as fibres coating. However the matrix porosity was = 13%, which makes it difficult to interpret the results, because the toughness cannot be unambiguously attributed to the properties of the unstabilized zirconia interfaces. In this work, model composites with dense alumina matrix and single alumina fibres were fabricated. The fibre-matrix interface was produced via dip-coating single fibres in monoclinic zirconia suspensions. Different particle sizes were used for the dip-coating in order to vary the coating porosity. The interfacial sliding stress was determined via a modified fibre pushin test. The crack deflection behaviour was analysed from cracks created via Vickers indentations and the fibre pullout via surface fracture observations. Properties such as fracture toughness, hardness and elastic modulus for the interface and matrix were also evaluated in order to determine the crack deflection parameters established by He and Hutchinson.

Повний текст джерелаComposite material components are produced in a near final shape. Machining operations such as drilling are often indispensable, namely for joining of structures. This process introduces damage along the periphery of the hole. Different methods to reduce this induced damage were developed. However, difficulties arise when comparing them since delamination is irregular in shape and in size. The delamination factor and the adjusted delamination factor quantify the damage but none achieved full acceptance since no international standards have been set. The aim of this work is to develop an image processing methodology associated with digital radiography that is capable of assessing the drilling induced damage in CFRP, being easily reproducible and allowing comparison of different drilling approaches. The subtraction of pre and post drill radiographies defined the target image to reach. In the image processing the threshold was found to be the most influential variable causing significant changes to the delamination factors. A new approach to the delamination factor is proposed in order to characterize the drilling induced damage. This approach allows the minimization of the quantified damage for the most irregular delamination shapes while equalling the current delamination factors for regular (crown like) damages.
