“…Another commonly used parameter is the ratio n 2 /A eff , which takes the value of 4.86 ϫ 10 Ϫ10 W Ϫ1 . The value of the linear polarization refractive index lies within the 2.6 -3.3 ϫ 10 Ϫ20 m 2 W Ϫ1 range of previously published reports [1,3,5,9]. Figure 4 presents the calculated power evolution along the fiber for the input and first-order FWM product mixing signals.…”

The simultaneous measurement of the nonlinear refractive index and the chromatic dispersion measurement of dispersion shift fibers are proposed, based on the power determination of the mixing products generated by four pump waves. This method is also used with other low‐dispersion chromatic dispersion fiber, such as nonzero dispersion shifted fibers. © 2002 Wiley Periodicals, Inc.

“…The nonlinear coefficient of the fiber is approximately 18 (W km) −1 measured by analyzing the self-phase modulation induced nonlinear phase shift from a dual frequency continuous wave source [17]. There are many alternative ways to measure the nonlinear coefficient [18][19][20][21][22][23][24][25][26][27][28] and other techniques has resulted in higher values of more than 24 (W km) −1 illustrating the difficulties comparing nonlinear fibers, where the nonlinear coefficient has been measured with different techniques. The nonlinear coefficient is two times higher than for standard highly nonlinear fibers.…”

Owing to the unique dispersion properties and high nonlinear coefficient, the small-core nonlinear photonic crystal fiber is among the most studied type in the class of microstructured fibers. We present a review of the basic aspects of nonlinear photonic crystal fibers with focus on dispersion design. The description of fiber design includes examples of fibers for use in both the telecom wavelength range and below. Moreover, we give an introduction to femtosecond supercontinuum generation and the effects of choice of pumping wavelength in relation to fiber dispersion. Finally, we present a range of application examples from the field of supercontinuum generation and telecommunication.

“…In Ref [Maz99], it is shown that the maximum gain in the modulation instability sideband g max is given by twice the product of the peak pump power P 0 and the nonlinear parameter, γ (g max ≡ g(Ω max ) = 2γP 0 ), so for a fibre length of L, the peak power in the modulation instability sideband P M I is given by…”

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.
