“…The unique properties of photonic bandgap fibers (PBF) have made them of interest for numerous application fields [1]. Implementation of PBF for wavelength filtering, chromatic dispersion control, sensing, and nonlinear applications have been demonstrated already and new application fields are to be expected in the near future [2,3]. Up to now, most work has been carried out on hollow-core photonic bandgap fiber (HC-PBF) made from silica glass.…”

We report on the fabrication and optical assessment of an all-solid tellurite-glass photonic bandgap fiber. The manufacturing process via a preform drawing approach and the fiber characterization procedures are described and discussed. The fiber exhibits some minor morphological deformations that do not prevent the observation of optical confinement within the fiber by bandgap effects. The experimental fiber attenuation spectrum displays clear bandgap confinement regions whose positions are confirmed by modeling the guiding properties of the ideal geometry using a plane-wave expansion method. The model identifies the bound modes of the structure and provides confirmation of experimentally observed mode field profiles.

“…Photonic crystal fibers (PCFs) also known as microstructured optical fibers, are currently under exhaustive study because several devices for optical processing of light can be designed and also due to their flexibility and the feasibility for tailoring their main properties (chromatic dispersion, modal area, single‐mode operation, etc.,) by adjusting their optical and geometrical parameters in a judicious way . They are classified in two categories according to their guiding mechanism: The holey fiber and the index‐guiding fiber, where the guiding mechanism is the photonic band gap and the total internal reflection, for the former and the later, respectively.…”

“…Several groups [153,154] have implemented a hybrid fibre structure whose cross-sectional profile consists of an array of high-index rods to achieve a photonic bandgap, whilst a secondary array of air holes in the interstitial sites could be used to tune the dispersion. These air holes also reduce the bend loss of the fibre by increasing the refractive index contrast between the guided mode of the core and the cladding supermodes [155] . This would in theory allow photon pair generation with very little Raman noise.…”

In recent years, there has been rapid development in processing of quantum information using quantum states of light. The focus is now turning towards developing real-world implementations of technologies such as all-optical quantum computing and cryptography. The ability to consistently create and control the required single photon states of light is crucial for successful operation. Therefore, high performance single photon sources are very much in demand.The most common approach of generating the required nonclassical states of light is through spontaneous photon pair generation in a nonlinear medium. One photon in the pair is detected to "herald" the presence of the remaining single photon. For many applications the photons are required to be in pure indistinguishable states. However, photon pairs generated in this manner typically suffer from spectral correlations, which can lead to the production of mixed, distinguishable states. Additionally, these sources are probabilistic in nature, which fundamentally limits the number of photons that can be delivered simultaneously by independent sources and hence the scalability of these future technologies.One route to deterministic operation is by actively multiplexing several independent sources together to increase the probability of delivering a single photon from the system. This thesis presents the development and analysis of a multiplexing scheme of heralded single photons in high-purity indistinguishable states within an integrated optical fibre system. The spectral correlations present between the two photons in the pair were minimised by spectrally engineering each photonic crystal fibre source. A novel, in-fibre, broadband filtering scheme was implemented using photonic bandgap fibres. In total, two sources were multiplexed using a fast optical switch, yielding an 86% increase in the heralded count rate from the system. AcknowledgementsI would first like to express my gratitude to my supervisor Dr. Peter Mosley, for giving me the opportunity to work with him on an exciting and interesting project, and for first introducing me to the world of quantum optics in the final year of my undergraduate degree. Without his support and guidance over the last three years, this thesis and the work that it contains would not have been possible. It has been a tremendously enjoyable learning experience (for both of us I hope!), and I think I can safely say that I now know more about FPGAs than I ever thought or hoped I would! I am incredibly grateful for the opportunity, and eagerly look forward to continue working with you on the upcoming NQIT project.Secondly, I would like to thank all of the staff and students, past and present, of the Centre for Photonics and Photonic Materials for providing an enjoyable, interesting and supportive learning environment. I would particularly like to thank James, for casting his eye over my fibre designs, passing down his fabrication knowledge, and teaching me the dark art of the dispersion rig! I would also especially like to ...
