Abstract:

This thesis is concerned with the realisation of an all-fibre acousto-optic device which can be used as a switch, filter, frequency shifter, polarisation controller or amplitude modulator, depending on the configuration. The devices are based on the acousto-optic interaction in fused tapered couplers and as such are completely compatible with fibre networks. For the first time polarisation insensitive devices have been realised by precisely controlling the degree of fibre fusion in an asymmetric coupler. This thesis details the theoretical considerations required to fabricate and operate all-f

Abstract:

This thesis proves that it is possible in principle to make in line optical fibre polarizers from tapered optical fibres surrounded by a quartz cladding. The theory of light propagation and polarization in fibres was reviewed as background information and several fabrication processes were evaluated and tried experimentally. The best results are obtained by heating a quartz tube in an oxy-propane flame, so that it collapses onto the fibre. Unfortunately, due to residues remaining between fibre and quartz tube, and due to large differences in melting points the results are quite irreproducible,

Abstract:

Tapered optical fibres have been manufactured, characterised and studied. These are compact devices made from single-mode optical fibre. A system for producing tapers has been developed, employing flame heating of the optical fibre and computer controlled rotation stages to stretch the fibre in a controlled and repeatable fashion. Subsequently tapered fibres were coated with nanostructured films of materials that change their optical properties in response to an external stimulus. An investigation of the effect of depositing chemically sensitive nano-scale films onto tapered optical fibres has

Abstract:

In this thesis we describe all-fibre devices that can be used for manipulating modes in a range of applications. The devices comprise an input and an output system and rely on fibre transitions. If the transition is gradual enough to be adiabatic, we can predict the behaviour of the output system depending only on the characteristics of the input system. Some of these devices work in a mode-selective regime where each input of the device excites a different mode at the output. These devices can be used to increase the data capacity of fibre networks where each mode can be used as an independen

Abstract:

The use of optical fibre as a mechanism for the delivery of the trapping laser beam to the sample chamber significantly reduces both the size and the build costs of “Optical Tweezers”. Furthermore, the use of fibre facilitates the decoupling of the optical trapping beam from the microscope optics, which provides further scope for the development of a portable optical trapping system, and the potential for uncomplicated integration with other advanced microscopy systems such as an atomic force microscope (AFM) for example. For use with an AFM, the optical fibre must be inserted at an angle of 1

Fiber optical temperature and strain sensors have been extensively investigated for applications in the civil structures to ensure safety and prevent disasters in advance. Most of the demonstrated fiber sensors are based on the silica fibers to form an interferometer by measuring the spectrum wavelength shift caused by the change of the refractive index and fiber length, and the sensitivities, defined as the rate of wavelength shift with respect to temperature or strain, are limited by the small values of thermal-expansion coefficient and thermo-optic effect of the silica materials.

The purpose of this research was to determine the effect of diameter fluctuations on the sensitivity of sapphire multimode optical fibers used as evanescent wave fluorescence sensors. It was predicted that fluctuations in the diameter of the fiber would act as a series of bi-tapers converting lower order modes to higher order modes increasing the evanescent wave penetration depth thereby increasing the excitation of a cladding of fluorescent fluid. Induced fluorescence from the fluid cladding would then couple back into the fiber more efficiently increasing the sensitivity of the sensor. The e

Thanks to their capability of transmitting light with low loss, optical fibers have found a wide range of applications in illumination, imaging, and telecommunication.

Abstract:

碩士<br>國立中正大學<br>物理所<br>97<br>A fiber biosensor modified by nano-gold particles is made according to the localized surface plasma resonance theorem. The nano-gold particles enhances the sensitivity of the sensor measuring the refractive index (RI) by absorbing and scattering the evanescent wave on the interface between the core and the liquid to be tested. Different research teams have used different approaches to achieve the same goal. In this study, we pursue our goal by modification of the fiber with nano-gold particles. This fiber is either tapered or non-tapered in advance. Note that tap

Abstract:

碩士<br>國立陽明大學<br>生醫光電研究所<br>100<br>To measure liquid refractive index is important in applications. The traditional method for the measurement of refractive index (RI) is measuring the critical angle or Brewster’s angle. In this experiment, the tapered fiber sensor adapting “End-etching method” was coated with hot melt glue for chemical etching, the capillary effect to form a sharp tip. The tip size was about 80 to 100 nanometers and with a rough surface when we observed by the SEM. The tapered fiber is a label-free and metal-free sensor. The test method is optical spot confined in the tip. Th
