Over the past twenty years, hollow core fibres have been one of the most exciting innovations in optical fibre technology. Hollow core fibres have extended the optical properties achievable in conventional step-index fibres and open up new applications such as non-linear optics. Despite numerous breakthroughs, the fabrication process of such fibres remains time consuming and costly.

I explore the use of polymers, which can be 3D printed using the inexpensive fused deposition modelling technique. As polymers have high absorption across the electromagnetic spectrum, I focus on hollow core fibre designs. Using finite element simulations, I propose a novel antiresonant fibre design that can be fabricated using additive manufacturing. The detailed simulations of this design give a new understanding of the effect of the cladding elements' curvature has on the leakage loss of the structure.

Several fibre preforms are successfully fabricated using different polymers. To understand the drawing process required for these materials, systematic drawing experiments are performed to aid the understanding of the fundamental differences between glass and polymer fibre fabrication. I developed a fluid dynamics model that is validated experimentally to predict the polymer capillary drawing process, taking into account the Non-Newtonian shear-thinning behaviour of these materials.

To further demonstrate the capabilities of additive manufacturing for photonic components, I design, fabricate and characterise a novel hollow core waveguide for the terahertz regime. These waveguides have the potential to replace costly terahertz components and detailed simulations suggest their attenuation can be improved by orders of magnitude with improvements in the quality of the fabrication process.

Abstract

Over the past twenty years, hollow core fibres have been one of the most exciting innovations in optical fibre technology. Hollow core fibres have extended the optical properties achievable in conventional step-index fibres and open up new applications such as non-linear optics. Despite numerous breakthroughs, the fabrication process of such fibres remains time consuming and costly.

This thesis describes the use of additive manufacturing as a fabrication method for hollow core fibre preforms and waveguides. I explore the use of polymers, which can be 3D printed using the inexpensive fused deposition modelling technique. As polymers have high absorption across the electromagnetic spectrum, I focus on hollow core fibre designs. Using finite element simulations, I propose a novel antiresonant fibre design that can be fabricated using additive manufacturing. The detailed simulations of this design give a new understanding of the effect of the cladding elements' curvature has on the leakage loss of the structure.

Several fibre preforms are successfully fabricated using different polymers. To understand the drawing process required for these materials, systematic drawing experiments are performed to aid the understanding of the fundamental differences between glass and polymer fibre fabrication. I developed a fluid dynamics model that is validated experimentally to predict the polymer capillary drawing process, taking into account the Non-Newtonian shear-thinning behaviour of these materials.

To further demonstrate the capabilities of additive manufacturing for photonic components, I design, fabricate and characterise a novel hollow core waveguide for the terahertz regime. These waveguides have the potential to replace costly terahertz components and detailed simulations suggest their attenuation can be improved by orders of magnitude with improvements in the quality of the fabrication process.
