Full textThe aim of the work presented in this thesis is to develop a new version of a multimode fiber optic gyroscope based on the optimal choice of the optical components and the signal processing. The work is mainly divided to two parts. The first part is devoted to the modeling of multimode Sagnac interferometer and allows the study of the effect of the modes coupling on the gyroscope performances. The modeling results are used to optimize the choice of the gyroscope components. The second part is dedicated to the experimental setup of the new prototype of the gyroscope and for the performances characterization

Full textThis work focuses on the thermomechanical modeling of fiber-optic gyroscopes (FOG), in order to improve the prediction of thermally-induced measurement biases. A multi-scale approach is developed to predict and understand these biases.First, the operation of fiber-optic gyroscopes, based on the Sagnac effect, is presented, along with the effect of thermal changes on the measurement.A numerically expensive axisymmetric finite element model is developed to predict these thermal biases.A homogenized transversely isotropic thermomechanical model of the coil is identified and used to predict thermal biases. This experimentally validated approach enables a drastic reduction in computational costs.A mixed model is developed to overcome the limitations of the homogeneous model at low temperatures, combining a homogeneous description of the bulk of the coil and a fine description of its edges.An averaging coupling strategy is proposed, offering an excellent compromise between accuracy and numerical efficiency.For disordered coils, where the theoretical winding pattern is not respected, an X-ray tomography reconstruction method is developed, enabling us to characterize their real structure and feed the thermomechanical models.These developments provide powerful numerical tools for predicting thermal bias in FOGs, contributing to improving their performances for inertial navigation

Thesis, Toulouse, INPT, 2019. http://www.theses.fr/2019INPT0022.
Full textRefractive index measurement has been studied since Ernest Abbé initially designed a refractometer in 1869, which is named the Abbé refractometer. Since then, numerous types of refractometers have been developed by employing either the optical prism-based refractometer or the optical fiber-based refractometer, due to their wide-ranging applications such as for sensingvarious physical, biological and chemical parameters. Recently, a large number of researchers have been developing refractometers based on optical fibers, exploiting mechanisms such as surface plasmon resonance (SPR), multimode interference, fiber Bragg gratings (FBG), long period gratings (LPG), tapered optical fibers, and striped-cladding multimode fibers (MMF), for their advantages in immunity against electromagnetic interference, electrical passivity at the sensing probe, and capability to long term in-situ measurement. This thesis concerns the development of comprehensively functional and accurate models for optical fiber refractometers based on optical intensity modulation, in particular for stripped-cladding MMF refractometry as well as hybrid systems involving a combination of single-mode-multimode fiber refractometery and the all-fiber hybrid refractometer using photonic crystal fibers. A key objective of this work is to characterize the performance of these intensity-based optical fiber refractometers in terms of their power response, sensitivity, resolution, and dynamic range. The simulation results which are corroborated experimentally demonstrate very high sensitivity being obtained in Zone II (i.e. the sensing regime typically employed for measuring a sensing medium index higher than the cladding index but less than or equal to the core index) for all three types of refractometers. However, the sensitivity in Zone III (i.e. the sensing regime for which the sensing medium index is higher than the core index) is very low. A hybrid single-mode fiber - multimode fiber configuration is used to improve the sensitivity in Zone III. On other hand, the sensitivity for Zone I (i.e. the sensing regime typically employed for measuring a sensing medium index lower than the cladding index) has been improved by increasing evanescent wave absorption using the all-fiber hybrid refractometer based on solid-core photonic crystal fibers. As a further potential of the fiber refractometer for applications in biochemical sensing, the proof-of-concept for a methane gas sensor has been demonstrated using supramolecular cryptophane-A which enables to trap the methane molecules. Cryptophane-A incorporated into a functionalized film of StyreneAcrylonitrile (SAN) host is applied to a de-cladded region of the sensor as the sensitive region. The refractive index of this functionalized layer increases proportionally with increasing methane concentration, subsequently inducing variations in the transmitted optical power along the fiber sensor

Full textIn this manuscript, we report the theoretical and experimental developments at TRT, TAV and LAC, aiming the realization of a hollow-core passive resonant fiber optical gyroscope that can achieve navigation grade performances. We mathematically describe the Sagnac effect, which is a relativistic effect used to optically probe mechanical rotations. Then, we detail the state of the art in passive resonant fiber optical gyroscope development. We identify their limitations, and explain why the hollow core fiber seems to be the best solution to cope with the actual limitations of such gyroscopes. We then focus on two different types of hollow core fibers: Kagome and photonic bandgap. We evaluate their performances in terms of transmission, polarization holding and backscattering. We describe the first measurement of a lock in region in a hollow core fiber passive optical gyroscope, i.e the range of rotation rates that cannot be measured because of backscattering. A mathematical model is propounded to link the lock in to the backscattering of the cavity. We then discuss the experimental protocol that we implemented to circumvent this limitation. Finally, we characterize the performances of our gyroscope based on these features

Full textApplications such as pollution control or countermeasures have a need in mid infrared sources (2. 5-5μm). Nowadays, compact, robust sources with a good beam quality are not available in this spectral range. To overcome this limitation, we study the conversion of usual sources by stimulated Raman scattering in hollow-core fibre. A proposal uses a hydrogen-filled tapered hollow-core photonic bandgap fibre as a wavelength converter. First results demonstrate the ability to convert the pump toward fifth Stokes order with a monomode beam profile. Then, large pitch hollow-core fibre allowing air-guiding over a broad spectral range are studied. Characterisation of the fabricated fibres paves the way to stimulated Raman scattering with large shift gases

Full textThe work presented in this thesis relates the development of a dual frequency comb spectrometer based on the electro-optic modulation of a continuous wave laser, and its utilisation for spectroscopic applications in the near- and mid-infrared.Since their discovery in the 1960s, frequency combs have revolutionised the physics, especially in metrology but also in spectroscopy, which lead to the Nobel Prize in Physics in 2005. In this domain of applications, dual frequency comb spectrometers are known to be complex to develop and use. A possibility to bypass these constraints is to build the spectrometer with electro-optic modulators. This particular architecture makes the experimental setup easy to use, thanks to the all-fibered feature and the lack of enslavement needed.In this manuscript, the work related describe first the architecture of a dual-comb spectrometer based on electro-optic modulators. We will see the advantages and disadvantages of the technique, especially for spectroscopic applications. We will also see the benefits of nonlinear phenomena in optical fibers to improve the experimental setup. Then, we show how the spectral range of the spectrometer can be extended around 2~µm, either by direct electro-optic modulation, or by frequency conversion in specific optical fibers.Finally, we will see the possibility to reach the mid-infrared by using nonlinear crystals. This last spectral extension will allow us to probe a spectral region highly suitable for spectroscopy, and hence to realise specific applications such as exhaled breath analysis
