Abstract:
Guided waves have been extensively studied in the past few years, and more recently nonlinear guided waves have attracted significant research interest for their potential for early damage detection and material state characterization. Combined harmonic generation due to wave mixing can offer some advantages over second harmonic generation. However, studies focused on Lamb wave mixing are still very limited, and have mainly focused on collinear wave mixing and used plane wave assumption. In this paper, numerical simulations and experiments are conducted to understand the interaction of mixing non-collinear Lamb wave pulses with non-planar wavefronts. The results demonstrate that the generated secondary wave is cumulative under internal resonance conditions and the sum-frequency component of the combined harmonics is useful for characterizing material nonlinearities.

Abstract:
Bolted joints are fundamental to numerous structural components in engineering practice. Nevertheless, their failure or even their loosening can lead to insufficient performance and reduced structural safety. This study presents a theoretical development and experimental investigation into nonlinear guided-wave mixing for integrity monitoring of bolted joints in plates. Combinational harmonics generated due to nonlinear Lamb wave mixing and contact acoustic nonlinearity at the bolted joints were used to evaluate the applied torque level in the joint. The area of the power spectral density in the region of the sum combinational harmonic bandwidth is found to be highly correlated to the applied torque level at the joint. Moreover, the effect of the number of cycles and thus the time duration of the excitation is investigated. The results show that the combinational harmonics remain robust for different numbers of cycles in detecting bolt loosening. The findings presented in this study also provide physical insight into the phenomena of nonlinear Lamb wave mixing for evaluating applied torque in bolted joints, and the results help further advance the use of nonlinear guided waves for damage detection.

Abstract:
Ultrasonic non-destructive testing is an effective means of examining objects without destroying them. Among such testing, ultrasonic nonlinear evaluation is used to detect micro-damage, such as corrosion or plastic deformation. In terms of micro-damage evaluation, the data that comes from amplitude comparison in the frequency domain plays a significant role. Its technique and parameter are called ultrasonic nonlinear technique and nonlinearity. A certain portion of nonlinearity comes from the equipment system, while the other portion of nonlinearity comes from the material. The former is system nonlinearity, while the latter is material nonlinearity. System nonlinearity interferes with interpretation, because its source is not from the material. In this study, in order to minimize system effects, a mixing technique is implemented. To use the large area inspection ability of the guided wave, the main research issue in this paper is focused on the guided wave mixing technique. Moreover, several bulk wave mixing theory equations become good concepts for guided wave mixing theoretical study, and the conventional nonlinear technique and guided wave mixing experimental results are compared in this study to confirm the reliability. This technique can play an important role in quantitatively discriminating fine damage by minimizing the nonlinearity of the equipment system.

Abstract:
We review the use of hollow waveguides for frequency conversion of ultrafast laser pulses the ultraviolet and extreme ultraviolet. Phase-matching of these processes is reached through a balance of gas and waveguide dispersion. By mixing 400 nm with 800 nm light, ultrashort (8 fs) pulses are generated near 270 nm with high efficiency > 20%. Tuning of the longer-wavelength component in the mixing process allows tuning of the output from 215–308 nm. In the XUV, this guided-wave phase-matching has allowed an increase of conversion efficiency of high-order harmonic generation of 100–1000x over that obtained with a gas jet, in an experimentally-convenient geometry.

Abstract:
The incentive for conducting Degenerate Four Wave Mixing (DFWM) within guided wave devices is two-fold: (1) By coupling the optical beams into guided wave devices, the optical power densities can be increased orders of magnitude due to the tight confinement of the beams. Such an increase in power density means a concomitant increase in conversion efficiency of the signal beam. (2) The potential signal processing applications of DFWM (logic gates, switching, correlation/convolution), particularly for ultra-fast serial processing, would be better exploited, and adjoined to existing integrated circuit technology, by such an integrated optic/guided wave approach. In this dissertation we describe experiments and present data confirming the presence of DFWM within a planar glass thin film with carbon disulphide as the nonlinear cover medium. Optical pulses from a Q-switched, frequency doubled Nd:YAG laser are coupled into the glass film. The nonlinear polarization required to produce the desired conjugate signal is generated within the CS₂ by the evanescent tails of the guided input beams as they probe the nonlinear cover medium. The signals measured agree well with theory, but because they were so small in magnitude, signal-to noise ratios were small due to stray background radiation scattering from beamsplitters and other associated optics. Additionally, recent studies (Jain & Lind, 1983) indicate nonlinear responses in semiconductor (CdS/Se) doped glasses, commercially available as color glass filters, that are orders of magnitude higher than corresponding nonlinearities within CS₂, in addition to possessing subnanosecond response times. We have performed experiments upon such glasses in an effort to fabricate nonlinear optical waveguides within them via ion-exchange techniques. We have successfully fabricated single mode planar guides, but they are currently too lossy to allow demonstration of any guided wave nonlinearities. Also, we describe experiments in which we have measured (bulk) DFWM grating lifetimes with greater precision than previously reported. Results indicate a fast (20 to 50 pico-seconds, depending on the particular glass) electronic response, superimposed upon, but clearly distinguishable from, a slower (10's of nanoseconds) thermal response.

Resumo: As micro-cavidades ópticas são componentes essenciais em sistemas ópticos integrados, pois elas permitem capturar seletivamente, liberar e armazenar fótons, além de promoverem suas interações. Como exemplo, os micro-discos e micro-anéis são elementos que proporcionam tempos de vidas fotônicos extremamente longos, que podem ser utilizados tanto para filtros espectrais quanto para interações de fótons com alta eficiência não linear. Seu pequeno volume e seu alto tempo de vida fotônico são importantes para promoção eficiente de efeitos ópticos não lineares e, especialmente, o processo de mistura de quatro ondas com uma única freqüência de bombeio. No entanto, acoplar luz em um ressonador ainda é realizado com integrações híbridas utilizando fibras estranguladas. Nesta dissertação, nós apresentamos uma nova técnica para a fabricação de estruturas com ressonadores integrados monoliticamente a guias de ondas planares estrangulados, baseados em camadas de Si3N4/SiO2 depositadas sobre silício. Para isto, foi utilizada uma técnica que combina a nano fabricação, baseada em corrosões com um feixe de íons focalizados (FIB), com a técnica convencional de micro fabricação. Utilizando esta combinação, foi possível fabricar ressonadores acoplados a guias de ondas estrangulados e caracterizá-los. Para finalizar, nós observamos a geração de fótons em uma ressonância de um micro-anel devido ao efeito não linear de mistura de quatro ondas gerada pelo bombeio em uma ressonância subseqüente do anel
Abstract: Optical microcavities are essential components in optical integrated systems for they provide selective capture, release, and storage of photons as well as interaction with matter and other photons. As an example, micro-disks and micro-rings are elements that provide extremely long photon lifetime that can be used for spectral filtering as well for highly efficient non-linear photon interaction. For instance, its small volume and the high photonic lifetime are very important for the efficient promotion of nonlinear effects and, specially, the four wave-mixing (FWM) process with a single pumping frequency. However, coupling light to and from the resonator is still achieved with hybrid integration using tapered silica fibers. But, in this dissertation, we present a new technique for the fabrication of structures with monolithically integrated resonators and planar tapered waveguides, all based in Si3N4/SiO2 layers deposited on silicon. We use an approach that combines nano fabrication techniques based on focused ion beam (FIB) milling and conventional micro fabrication techniques. Using this approach, we could fabricate resonators coupled to tapered waveguides and characterize them. Finally, we observed the photon generation at a micro-ring resonance due to four-wave mixing generated by pumping at a subsequent micro-ring resonance

Abstract:
Thin-walled components are fundamental to numerous civil structures such as bridges, buildings, storage vessels, pipes, and becoming progressively diverse with their use in wind turbines, aircrafts and shipbuilding. Identification and evaluation of damage in such structures plays a significant role in the early stage of the project conception, given that safety, performance and maintenance costs are three fundamental concepts in any engineering design. Structural Health Monitoring (SHM) was originated with collaboration across many disciplines to address a variety of structural issues and prevent dramatic losses. Nonlinear guided waves combines the benefits of nonlinear ultrasound and guided waves. By means of linear parameters such as wave reflection, attenuation and transition, wave velocity, or wave modes, linear guided waves cannot detect microscale damage such as early stage fatigue, corrosion, micro-crack, or microdelamination. In contrast, nonlinear guided wave have resulted promising due to incipient damage detection capabilities and reference-free potential, and leveraged its advantages over linear guided waves. This thesis investigates the use of nonlinear guided waves via a wave-mixing approach, where two ultrasonic frequencies are used, and the spectral content of the response is expected to carry information of the damage. This thesis provides a physical insight into the wave-mixing technique for damage detection in structures. The phenomenon is investigated theoretically, numerically and through laboratory experiments. A number of published and prepared journal papers under the same topic is included in this thesis. In Chapter 1, an overview of the general concepts of Structural Health Monitoring and connected non-destructive testing techniques are introduced along with nonlinear guided wave techniques. A theoretical derivation to correlate the contact effect on a steel bolted joint with the spectral content of a signal response is proposed in Chapter 2. Thorough experiments were carried out and demonstrated the robustness of the technique. Following, in Chapter 3, identification of debonding type of damage in adhesively bonded joints is investigated through three-dimensional finite element simulations and experiments. Numerical and experimental results revealed that guided wave-mixing technique could effectively detect debonding damage. To further extend the advantages of guided wave-mixing for different materials, a composite laminate plate in studied in Chapter 4. In this study, an imaging technique relying of the combined frequency wave is proposed to identify delamination and locate the defect. The proposed approach relies on network of few transducers and does not require reference data from undamaged samples. Lastly, a short study is presented in Chapter 5, where noncollinear pulses of finite time duration and non-planar wave-front are able to generate a resonant wave that is able to measure material nonlinearity, which is subject of study for many early stage fatigue damage detection techniques. Overall, this thesis systematically revealed and capitalized the advantages of nonlinear guided wave-mixing technique for various types of damage in structures across a wide variety of materials.

Abstract:
Non-destructive testing plays an important role in structural health monitoring. One of the promising options is the use of guided wave for damage detection in engineering applications, such as pipeline and truss system. Common types of damage in the structures include cracks and corrosion. Guided wave is sensitive to cracks up to micro scale. Long range inspection is the other benefit of using guided wave. The overall aim of this thesis is to present a systematic investigation of guided wave in pipe-like structures to gain physical insights into linear and nonlinear features associated with torsional guided wave interaction with damage. This thesis includes a number of published and prepared journal papers under the same topic. The overview of linear and nonlinear guided wave, and guided wave mixing is introduced in Chapter 1. A computational model using one-dimensional time-domain spectral finite element with cracked element is presented in Chapter 2. This chapter mainly focuses on linear features of guided wave, such as scattering and mode conversion phenomena. The results show that the proposed cracked model has good agreement between the experimental results and three-dimensional (3D) finite element (FE) simulations. Nonlinear guided wave is highly sensitive to early stage of micro cracks. Material nonlinearity is one of the nonlinear phenomena in the presence of the micro cracks. It can induce higher-order harmonics of guided wave. Guided wave mixing is the advanced version of nonlinear guided wave since the generation of combinational harmonics at sum and difference frequencies can minimise the effect due to the nonlinearity generated by equipment. Chapter 3 analyses the nonlinear characteristics of two interacting fundamental torsional guided wave modes numerically and experimentally. Chapter 4 and Chapter 5 are the extension parts based on the work in Chapter 3 since pipe-like structures are commonly used in many circumstances, for example embedded pipes and pre-stressed hollow structures. Comprehensive studies in this thesis can gain more understanding for the real applications. In Chapter 4, a 3D FE embedded pipe model with the implementation of nonlinear strain energy function is established to simulate the energy leakage of guided wave propagation due to the existence of soil media. The use of 3D laser scanning system receives guided wave signals from the surface of the pipe for verification. Both numerical and experimental results indicate a significant decline in the interested harmonics at mixed frequency and single frequency. On the other hand, acoustoelastic effect is studied in Chapter 5. A series of case studies are carried out to observe the group velocity change with respect to different levels of loading. The nonlinear features, such as combinational harmonics and second harmonics, are also investigated numerically and experimentally.
