“…The standard way of manufacturing PCF involves two main steps: fabrication of a fiber-preform and drawing by using a high temperature furnace in a standard fiber drawing tower. Firstly, various vapour deposition techniques are established for the fabrication of fiber performs, such as modified chemical vapour deposition (MCVD), vapour axial deposition (VAD), and outside vapour deposition (OVD) [21]. These techniques allow for the fabrication of preforms with silica glasses having very low, un-intentional, impurity levels, and precisely controlled doping levels.…”

A numerical analysis on dual core photonic crystal fiber (DC-PCF) based surface plasmon resonance (SPR) refractive index sensor is presented. The guiding parameters and required sensing performances are examined with finite element method (FEM) based software under MATLAB environment. According to simulation, it is warranted that the proposed refractive index sensor offers the maximum amplitude sensitivity of 554.9 refractive index unit (RIU −1 ) and 636.5 RIU −1 with the maximum wavelength sensitivity of 5800 nm/RIU and 11 500 nm/RIU, and the sensor resolutions of 1.72 × 10 −5 RIU and 8.7 × 10 −6 RIU, at analyte refractive index (RI) of 1.40 for x-and y-polarized modes, respectively. As the sensing performance in different wavelength ranges is quite high, the proposed sensor can be used in simultaneous detection for different wavelength ranges. Therefore, the proposed device is of a suitable platform for detecting biological, chemical, biochemical, and organic chemical analytes.

“…Two parameters are used to characterise this structure: the hole diameter d and the centre to centre hole spacing (pitch) Λ, typically ranging from 1 to 10 µm. A variety of PCFs have been manufactured with air-filling fractions, d/Λ of less than 0.1 to over 0.9 [Bja03]. This structure can lead to a much larger refractive index difference (∼ 25%) than conventional step-index fibres (∼ 4%) [Rus06].…”

Nonlinear optics enables the manipulation of spectral and temporal characteristics of optical pulses interacting with a dielectric medium. Optical fibres, as a uniquely practical medium, provide an environment for effectively exploiting the nonlinear effects. This has facilitated the rapid growing interest in this field focused on the investigation of fibrebased sources incorporated with various novel saturable absorber devices for ultrashort pulse generation.This thesis reports a series of experiments exploring the ongoing research in the field of nonlinear optics, including the development of ultrafast mode-locked fibre sources and their applications in supercontinumm generation and third order parametric interactions in new carbon materials.Firstly, the integration of carbon-based materials with rare-earth doped media allows the demonstration of ultrafast mode-locked laser sources operating at wavelengths across the near-infrared region in a compact, low cost and environmentally robust scheme.Power scaling of such sources can be achieved by operating in the all-normal dispersion regime making use of a glass-substrate saturable absorber device that exhibits a higher damage threshold.Supercontinuum generation has been used as an effective method for spectral broadening. Pumping with a conceptually simple and reliable fibre-based system, a continuum covering from 2 to 3 µm is generated in a highly nonlinear GeO 2 fibre. This experiment demonstrates a robust and long-term stable source of radiation in an important band, coincident with a portion of the atmospheric transmission window.Finally, the demonstration of a simple and compact nano-material based dual-wavelength system shows the performance of such devices as a simultaneous saturable absorber and passive synchroniser. An experimental study of coherent frequency mixing at large frequency shifts in a graphene sample, pumped by a two-colour fibre-integrated source, proves the strong nonlinear response of this new carbon material.

In particular, I would like to thank Ed for providing me with much needed support, interesting discussions (especially on food and culture) and continued collaboration since I joined the group. Tim, for making couplers for the Tm-system. Thanks to Tim, Robbie (shared the same office over the past three years!), Ed, and Rob for endless support, spending hours and hours proof reading chapters of this thesis and cheering me up all the time. Thanks to the visitor from A*STAR (Singapore), Dr. Dora Hu (more like a sister), for proof reading and encouraging me to relax during the thesis writing.

“…Current methods to create the preform, however, grant only limited freedom in the design of the preform [9]. Additionally, during the drawing process, the preform geometry is generally not preserved due to material viscosity, gravity, and surface tension effects [10]. Therefore, obtaining the desired PCF cross-sectional structure is not a straightforward process, and can be especially difficult.…”

Optical waveguide segments based on geometrically unbound photonic crystal fiber (PCF) designs could be exploited as building blocks to realize miniaturized complex devices that implement advanced photonic operations. Here, we show how to fabricate optical waveguide segments with PCF designs by direct high-resolution 3D printing and how the combination of these segments can realize complex photonic devices. We demonstrate the unprecedented precision and flexibility of our method by fabricating the first-ever fiber polarizing beam splitter based on PCFs. The device was directly printed in one step on the end-face of a standard single-mode fiber and was 210 µm long, offering broadband operation in the optical telecommunications C-band. Our approach harnesses the potential of high-resolution 3D printing and of PCF designs paving the way for the development of novel miniaturized complex photonic systems, which will positively impact and advance optical telecommunications, sensor technology, and biomedical devices.
