Abstract:
The work within this thesis investigates the characteristics and sensing properties of novel near- and mid-infrared tellurite and germanate glass fibres and their potential as sensing elements. An asymmetric splicing method for fusion-splicing tellurite and germanate glass fibres to standard silica fibre is demonstrated. The thermal and strain sensing properties of these glass fibres have been studied by analysing the properties of optical fibre Fabry-Perot cavities, which were formed when these high refractive index fibres were spliced to silica fibre, and fibre Bragg gratings.

Abstract:
In this thesis, an investigation into the modal characteristics of novel beam shapes is presented. Sculpting the phase profile of a Gaussian beam can result in the generation of a beam with unique properties. Described in this thesis are Laguerre-Gaussian (LG), Hermite-Gaussian (HG) and Bessel beams (BBs). The diffraction of LG beam modes from a triangular aperture is explored and this effect can be used for the efficient measurement of the azimuthal mode index l that indicates the number of multiples of 2π of phase changes that the field displays around one circumference of the optical axis.

Abstract:
Solar energy via photovoltaic (PV) is a promising and freely accessible energy source that has become the main route for managing long term challenges in the energy crisis. Organic solar cells (OSCs) have raised interest in the scientific community due to their enormous potential in solar industry such as mechanical flexibility, exceptional processability, and capability of large-area roll-to-roll (R2R) manufacturing. In this work, we emphasize to understand the correlation between optical (absorbance and photoluminescence) and morphology properties of air processed photoactive layer, which a

In order to solve these problems, the OCB cell having high pretilt splay or twist state is developed by using polymer stabilization method (PS). In this experi
