“…A pump source near 1550 nm has led to spectral broadening towards visible wavelength, on the contrary a pump source near 2000 nm limits broadening towards blue wavelength to 1700 nm [15,[17][18][19]. The measured ZDW of GeO 2 glass is around 1.73-1.74 μm, however for a GeO 2 doped fiber, the ZDW will depend on the exact concentration of GeO 2 (as it decides NA of fiber as well) and core diameter.…”

“…Later on, these fibers were characterized for SC experiments at different groups. In 2012, Kamynin et al pumped a 64 mol % Ge-doped fiber by a pump source lasing at 1.59 μm with pulse width of 35 ns at a repetition frequency of 4.4 kHz [15]. A spectrum ranging from 800 nm to 2700 nm was obtained from a 7 m fiber with a maximum output power of 500 mW.…”

Abstract:We demonstrate highly germania doped fibers for mid-infrared supercontinuum generation. Experiments ensure a highest output power of 1.44 W for a broadest spectrum from 700 nm to 3200 nm and 6.4 W for 800 nm to 2700 nm from these fibers, while being pumped by a broadband Erbium-Ytterbium doped fiber based master oscillator power amplifier. The effect of repetition frequency of pump source and length of germania-doped fiber has also been investigated. Further, germania doped fiber has been pumped by conventional supercontinuum source based on silica photonic crystal fiber supercontinuum source. At low power, a considerable broadening of 200-300 nm was observed. Further broadening of spectrum was limited due to limited power of pump source. Our investigations reveal the unexploited potential of germania doped fiber for mid-infrared supercontinuum generation. These measurements ensure the potential of germania based photonic crystal fiber or a step-index fiber supercontinuum source for high power ultra-broad band emission being by pumped a 1060 nm or a 1550 nm laser source. To the best of our knowledge, this is the record power, ultra-broadband, and all-fiberized supercontinuum light source based on silica and germania fiber ever demonstrated to the date.

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. Woodward who not only provided company inside and outside of the lab, but were also happy to discuss and help all matters of my work and life in UK. 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.
