Pham, Thi Nhung. "Fabry-Perot interferometer based on end-of-fiber polymer microtip for chemical sensing." Electronic Thesis or Diss., Bordeaux, 2024. http://www.theses.fr/2024BORD0006.
Fabry−Perot interferometers (FPIs) have received a significant attention for their use in sensor applications. FPIs consist of an optical cavity with separate parallel reflecting surfaces which reflect incident light, resulting in an optical interferometric signal. The FPI signal depends on the distance between the reflecting surfaces and the refractive index of the cavity medium, which are sensitive to variation of environment humidity, temperature, pressure, and material. FPIs can be attached to optical fibers to form compact fiber optic FPI-based sensors in which the optical fiber works as a waveguide for both incident and reflected signal. This thesis presents FPI-based chemical sensors incorporating a polymer microtip located at the end of an optical fiber and characterizes their sensing capabilities for humidity, water, and chemical targets.Firstly, we develop a pentaerythritol triacrylate (PETA) tip on the facet of an optical fiber by a self-guiding photopolymerization. One end of the optical fiber is placed inside a PETA droplet and the self-guiding photopolymerization of PETA is actuated by a 375 nm laser injected to the other end of the fiber. The optimal conditions to form a straight and mechanically stable PETA tip are 1.0 μW of laser power × 1.0 second of exposure time. However, the PETA chains do not completely polymerize during this self-polymerization, leading to an unstable dynamic resonant frequency of the tip. Thus, the tip needs a post-polymerization under a UV 365 nm lamp to achieve a stable dynamic characteristic, which is applicable for further sensing applications.Secondly, we demonstrate the PETA tip as an effective sensor to detect humidity. The PETA tip acts as an optical cavity formed between the fiber-core/PETA and the PETA/environment interface, resulting in a clear interferometric signal. The FPI signal of the tip is highly sensitive to humidity in the air. This is due to hydroxyl groups within the PETA structure, which strongly absorb water molecules in the humid air and significantly swell the tip. The length and/or the refractive index of the tip are therefore changed, resulting in a FPI shift. The tip exhibits a consistent sensitivity of 90pm/%RH, equivalent to a relative sensitivity of 104 ppm/%RH in the humidity range from 30 to 80%. The sensing performance is highly reproducible and stable. Furthermore, the cross effect of the temperature is negligible, indicating a great practical potential for the devices.Next, we apply the FPI-based PETA tips to determine the water content in glycerol and ethylene glycol solutions. The FPI signal of the PETA tip shifts nonlinearly towards longer wavelengths as the water content increases from 0 to 100 wt.%. The shift in the FPI signal occurs due to the contraction in the tip length, which is linked to the loss of water inside the PETA structure caused by the hydrophilic solutions. When the water contamination is below 10 wt.%, the tip shows a sensitivity of 394 pm/wt.% and 226 pm/wt.% for glycerol and ethylene glycol solutions, respectively. Therefore, the FPI-based PETA tip shows a great potential in determining water content in hydrophilic aqueous solutions, including hydrocarbons.Finally, a tip consisting of a PETA core and a shell of molecularly imprinted polymers (MIPs) is developed for detecting Dansyl-L-phenylalanine. The PETA tip is initially fabricated using the self-guiding polymerization and MIPs are then copolymerized to form a thin shell layer around the PETA tip. Upon the selective binding of Dansyl-L-phenylalanine, the refractive index of the MIP layer changes, leading to the change in the FPI signal of the whole PETA/MIP tip. This straightforward and affordable method offers new innovative possibilities for creating FPI-based MIP fiber optic sensors, which can be applied for a wide range of analytes, including both non-fluorescent and fluorescent targets

A practical fiber optic strain sensor has been developed to measure strains in the range of 0.0 to 2.0 percent strain with a resolution ranging between 10 and 100 microstrain depending on sensor design choices. This intensity based sensor measures strain by monitoring strain induced longitudinal misalignment in a novel fiber interconnection. This interconnection is created by aligning fibers within a segment of hollow core fiber. Related splice loss mechanisms are investigated for their effect on resolution. The effect of gauge length and launch conditions are also investigated.

Among the issues that are taken into consideration for many years by Engineers and Technologists is the integrity of the servicing elements in structures and mechanisms. It is a documented phenomenon that after a certain period of time, in service, engineering components tend to change their original state, and begin to develop faults and defects. This includes the original shape distortion due to effects such as bending, twisting, and cracks. The above-sited effects may be caused by the sudden or accumulative effect of overloading, thermal shocks, corrosion etc, which eventually lead to malfunction of these engineering components. The occurrence of the cracks may be as a result of stress variation in excess of different or similar materials; thermal shocks, vibration, etc. A system of structural health monitoring using optical fiber sensors to track down a crack occurrence and its propagation is considered to be a promising method in warning of catastrophic events. Taking advantage of optical fibers' properties and behavior, such as easy interaction with other materials, small size, low weight, corrosion resistance, geometrical flexibility and an inherent immunity to electromagnetic interference, there is potential in adopting the Fiber Optic Sensors (FOS) for structural health monitoring systems. Structural integrity does not confine itself to crack detection only. For example there are many instances where unwanted or excessive displacement may occur. Optical fibers play an important role in proximity sensing as evidenced in the literature [49] to [54] and available commercial systems. However it is felt that FOS displacement sensors may suffer in measurement accuracy due to in situ conditions.
