Abstract:
This thesis investigates new fibre technologies and their application in nonlinear optical systems, designed mainly for telecommunications. The thesis includes a study of two different directions in achieving a high nonlinearity in a fibre system, namely holey fibres filled with nonlinear liquids and soft glass, small core microstructured fibres. The challenges arising from the development of liquid-filled structures have made soft glass microstructured fibres the technology of choice for the realisation of highly nonlinear systems Amongst the various soft glasses, commercially available lead-silicate glasses are identified as the material for the development of highly nonlinear fibres. Small-core, leadsilicate fibres with different designs are considered within this thesis. A solid core holey fibre design as well as two all-solid designs, a multi-ring cladding and a simpler W-index profile, are characterised. The measurements confirm the advantages of the all-solid designs over the holey structures and reveal the possibility to achieve simultaneously a high nonlinear coefficient and a novel dispersion profile in such fibres. Some of the presented fibres are employed in all-optical wavelength conversion schemes based on fourwave-mixing. Numerical simulations and experimental results are combined to study the performance of the fibres and demonstrate their use in wavelength conversion devices. In particular, a lead-silicate W-index profile fibre, showing a high nonlinear coefficient of 820W−1km−1 with a near zero dispersion profile at telecoms wavelengths, is employed to demonstrate a flat conversion gain in the whole C-band. The same fibre is then employed in FWM-based systems to demonstrate multi-channel wavelength conversion, generation of high repetition rate pulses and all-optical demultiplexing. The experiments presented in this thesis clearly reveal the potential of small-core soft-glass fibres for nonlinear applications. The use of soft glass microstructured fibres in the mid-IR is also investigated. Tellurite holey fibres with different core sizes and hole arrangements are employed in a supercontinuum generation scheme.

Abstract:
Cette thèse présente des travaux portant sur l'instabilité modulationnelle (IM) dans des fibres optiques dotées à la fois d'une forte non linéarité et d'un fort coefficient d'absorption. Une analyse comparative des performances de plusieurs grandes classes de fibres (de verres silice et non silice) sur leur aptitude à générer des bandes latérales d'IM avec un minimum de puissance de pompe, et sur la plus courte distance possible, est effectuée. Les fibres de verres non silice de type Chalcogénure ou Tellure apparaissent à première vue comme étant les plus performantes, mais un examen attentif révèle que leurs spectres sont altérés par un phénomène de dérive en fréquence des bandes latérales d'IM, qui est provoquée par une forte absorption du laser de pompe. Nous développons alors une méthode qui permet de supprimer la dérive en fréquence des bandes latérales d'IM dans les fibres à fort coefficient d'absorption. Cette méthode, que nous avons baptisé "méthode du réservoir de photons", consiste à créer au sein de la fibre, par un ajustement approprié des paramètres de dispersion d'ordre deux et quatre, un réservoir de photons qui alimente in situ le processus d'IM en lui fournissant continuellement l'équivalent de la quantité de photons détruits par l'absorption matérielle au cours de la propagation. L'efficacité de la méthode du réservoir de photons est démontrée sur des processus d'IM aussi bien en configuration scalaire que vectorielle. Cette démonstration marque un progrès décisif vers des dispositifs de génération de fréquences optiques qui seront extrêmement précis et stables
This thesis considers modulational instability (MI) in optical fibers that have both a strong non-linearity and strong absorption coefficient. We carry out a comparative analysis of the performance of several major classes of silica- and non-silica glass fibers, on their ability to generate MI sidebands with a minimum of pump power, and over the shortest distance possible. Chalcogenide glass fibers appear at first sight as being the most competitive, but a careful examination reveals that their spectra are altered by a phenomenon of frequency drift of the MI sidebands, caused by a strong depletion of the pump. We have then developed a method which allows to suppress frequency drifts in MI processes in fibers having strong absorption parameters. The fundamental idea of this method, that we called "the photon reservoir method", is to create in the fiber, by an appropriate adjustment of the second-order and fourthorder dispersion coefficients, a photon reservoir which supplies (in situ) the MI process by continually providing the equivalent of the amount of photons destroyed by absorption during the propagation. We have demonstrated the effectiveness of the method of photon reservoir on MI processes, in scalarand vector configurations, using glass fibers endowed with extremely high nonlinear parameters. This method constitutes a decisive step forward in the development of highly competitive devices for optical frequency generation

Abstract:
Holey fibre (HF) is a new type of fibre that uses rings of air holes around a solid core toconfine light. A small core HF with a high air fill fraction can have effective nonlinearitycoefficient of around 10-100 times greater than conventional fibre. Apart from that, its dispersion value is also highly tailorable simply by changing the structural dimensions. These two characteristics make HFs attractive as a nonlinear medium. This thesis reports the first demonstration of various nonlinear fibre devices based on HFs. Thediscrete Raman amplifier is an attractive option to extend optical transmission systems into the optical communication bands outside the conventional erbium doped fibre amplifier (EDFA). We demonstrated a high gain discrete Raman L-band amplifier using a relatively short highly nonlinear HF. We also demonstrated a high extinction ratio, SRS based, intensity modulator using the same HF. Stimulated Brillouin scattering (SBS) is the most dominant nonlinear effect in optical fibres for a narrow linewidth system. SBS based devices could have an extremely low threshold value if highly nonlinear HF were to be used. We demonstrated a HF based Brillouin laser with a high experimentally observed threshold value. This is found to be mainly due to reduction in the effective gain coefficient caused by structural non-uniformity along the HF length. This has motivated us to study the relation between HF structural parameters and the Brillouin characteristics. This was done using two techniques: Brillouin optical time domain reflectometry (BOTDR) and the pump probe technique. A spectrally sliced pulse source is a cost effective solution to a multiwavelength transmitter. We demonstrated a HF based spectrally sliced pulse source. This was done by utilizing self phase modulation (SPM) to generate a supercontinuum in a normally dispersive HF before slicing the spectrum using an arrayed waveguide grating. Wavelength conversion is an important enabling technology for complex future optical networks. We showed in two separate experiments that by using a short length highly nonlinear HF, efficient wavelength conversion based on XPM as well as FWM can be achieved. A nonlinear thresholding device can improve the contrast of a pattern-recognition signature in an OCDMA system. Using a short highly nonlinear HF, we demonstrated a nonlinear thresholder for use in a super-structured fibre Bragg grating (SSFBG) based OCDMA receiver.

Abstract:
All-optical signal processing has recently become an attractive research field, a result of nonlinear optical systems making major advances in terms of cost, compactness, energy consumption, integrability and reliability. This technology has impacted several areas ranging from telecommunications and biomolecular sensing to military and quantum communications, and spanning a vast range of frequencies from the near to mid-infrared. This PhD research project was aimed at investigating the features and feasibility of two state-of-the-art all-optical signal processing technologies: highly nonlinear soft glass fibres and silicon-based waveguides. Of the various soft glasses available, lead silicate and tellurite are considered within this thesis. The optical properties of a highly nonlinear lead silicate W-type fibre are studied and the design process of such fibres is explained in detail. A number of telecommunications-based all-optical processing applications are also demonstrated in this fibre technology. Phase sensitive amplification is demonstrated in the W-type fibre and the process is used to regenerate the phase of 40 Gbit/s differential phase shift keying (DPSK) signals. The optical characteristics of a highly nonlinear tellurite fibre are also studied both at 1.55 and 2 µm. Efficient four wave mixing (FMW)-based wavelength conversion of 1.55 µm signals is demonstrated in the fibre and a detailed numerical study into the potential of the fibre in realizing phase-matched mid-infrared (MIR) to near-infrared (NIR) spectral translation is conducted. The second all-optical signal processing platform investigated in this project is silicon germanium (SiGe) waveguides. A detailed account of the linear and nonlinear optical properties of this newly emerging silicon-based technology is reported for the first time and the potential of this platform is highlighted by demonstrating wavelength conversion of 40 Gbaud DPSK and QPSK signals. Broadband spectral translation is also demonstrated in the SiGe waveguides with record FWM bandwidths.

Abstract:
Fiber optical parametric amplifiers (OPAs) are based on a highly-efficient four-wave mixing process. Their capability to give very high gain and large bandwidths have made them an attractive candidate for providing higher bandwidths for future telecommunication systems, such as wavelength-division multiplexed (WDM) photonics networks. In dynamic photonic networks a where number of channels are dropped and/or added all the time, the OPA gain for the other channels is affected. In this thesis we employed a well-known gain control technique, all-optical gain clamping (AOGC), and reduced the gain variation of fiber OPAs below 0.5 dB, under varying input conditions. We also showed an improvement in power penalties o at the bit-error rate of 10-8, from 2.5 dB to 0.5 dB for on/off keying modulation. We also investigated fiber optical parametric oscillators (OPOs). Using fiber OPAs as gain medium we realized two different continuous-wave (CW) OPOs, centred at 1561 nm and 1593 nm. One gave us watt-level output power from 1600 nm to 1670 nm, with overall tuning range of 211 nm. The output linewidth of signal and idler was measured to be 0.08 nm and 0.15 nm respectively. The OPO centred at 1593 nm gave us a record tuning range of 254 nm, and with 3 dB output coupling fraction, it gave us large output powers (20-27 dBm) from 1610 nm to 1720 nm. Using a large seed generated by a watt-level fiber OPO in the U-band, and using 3 W of CW pump source in the C-band for Raman amplification, we generated 3 W of CW output power. This gave us nearly 100% conversion efficiency. Launching a high-power CW pump with narrow linewidth into a fiber makes stimulated Brillouin scattering (SBS) a major problem. We investigated an SBS suppressor, based on a common technique of phase dithering of the pump to suppress the SBS. We compared a multitone modulation technique to modulation with a pseudo-random bit sequence (PRBS), and we showed that it can increase the SBS threshold by 4.18 dB, and is less expensive to implement.

Abstract:
Nonlinear fiber devices have been attracting considerable attention in recent years, due to their inherent ultrafast response time and potential applications in optical communication systems. They usually require long fibers to generate sufficient nonlinear phase shifts, since nonlinearities of conventional silica-core silica-clad fibers are too low. These long devices, however, cause the serious problems of pulse walk-off, pulse broadening, and polarization fluctuation which are major limiting factors for response time, switching bandwidth, and maximum transmittable bit-rate. Therefore, short device length is indispensable for achieving ultrafast switching and higher bit-rate data transmission. To shorten the required device length, fiber nonlinearities should be increased. In this dissertation, as a way of increasing fiber nonlinearities, high-nonlinearity materials of Litharge, Bismite, Tellurite, and Chalcogenide glasses have been considered. Although they have high nonlinearities, they also have high group-velocity dispersion and high losses deteriorating the performance of nonlinear fiber devices seriously. The aim of this work is to investigate how these high-nonlinearity glasses affect the performance of nonlinear fiber devices, taking into consideration both the advantages and disadvantages. To achieve it, the critical properties of various nonlinear fiber devices constructed with the different types of high-nonlinearity glasses and different types of fibers have been evaluated. It turned out that the required device lengths of nonlinear fiber devices constructed with the high-nonlinearity glasses were significantly reduced and high group-velocity dispersions and losses could not be major problems due to the extremely short device length. As a result, it would be possible to suppress the problems of pulse walk-off, pulse broadening, and polarization fluctuation in nonlinear fiber devices by introducing high-nonlinearity glasses, thus enabling ultrafast switching and higher bit-rate data transmission. Furthermore, in this dissertation, a new scheme of wavelength-division demultiplexing based on the optical Kerr effect has been proposed for the first time. The new scheme can turn the disadvantage of the extremely high group-velocity dispersion of high-nonlinearity glasses into an advantage of wavelength-division demultiplexing. Finally, it now would be possible to greatly increase maximum transmittable bit-rate in optical communication systems by simultaneously demultiplexing optical time-division-multiplexed signals and wavelength-division-multiplexed signals with an optical Kerr effect-based demultiplexer.

Abstract:
Two types of specimens were studied based on applying the nonlinear theory of flexible plates to obtain the interlaminar fracture toughness of layered composites. For a specimen of the thin sub-layer type, a theoretical solution was obtained in relation to the determination of the interlaminar fracture toughness for a mixed II/I mode. The fundamental possibility of using this solution in test practice was confirmed. The application of the nonlinear theory of flexible plates to the well-known standard specimen of the double-cantilever beam (DCB) was studied in more detail. A theoretical solution was obtained, an iterative algorithm for processing test results based on MATLAB code was developed, highly flexible glass fiber reinforced polymer (GFRP) specimens were tested and their comparison with the results of processing according to the ASTM D 5528-01 standard with correction of the linear solution was given.

Abstract:
The spatial and temporal characteristics of the internal temperature field of the box-type composite wall have great significance to high temperature mechanical response and fire resistance performance of composite wall subjected to fire. A series of assumptions for the simplified model were made after determining the influence of various thermal parameters, the boundary conditions of surface and the contact conditions. And the finite element software(ABAQUS) was used to establish the temperature field analysis model to conduct nonlinear transient temperature response analysis, then the validity of the model was verified by relevant test results. On this basis, the distribution of temperature field during the whole process and its key measuring points under fire are analyzed, and the parameters of each component are researched. The results show that the thickness of rock wool, the type, the thickness and number of layers of cladding plates have obvious influence on the temperature field distribution inside the composite wall, and other factors have little effect. According to the analysis results, the fire-resistant design idea of the composite wall and the temperature prediction formulas of the key temperature-control point are proposed, which provide the basis for the application of the boxtype steel structure system.
