Attosecond timing jitter modelocked lasers and ultralow phase noise photonic microwave oscillators
… noise coupled into phase noise through the self-steepening effect proves to be the major noise source. The most recent advance in silicon photonics and wafer-scale three-dimensional integration technology illuminates a pathway toward on-chip photonic microwave oscillators. Phase noise model …

Classical and quantum nonlinear optics in confined photonic structures
… is treated without approximation, and self-steepening is included. The feasibility of using a parametric down-conversion process to generate squeezed electromagnetic states in 3D photonic crystal microcavity structures is investigated for the first time. The spectrum of the squeezed …

Numerical and Analytical Studies of Electromagnetic Waves: Hermite Methods, Supercontinuum Generation, and Multiple Poles in the SEM
… Numerical simulations show that if the nonlinear self-steepening is strong enough, the model produces a shock that is not arrested by dispersion, whereas for weaker nonlinearity the pulse propagates the full extent of the fiber with the generation of a supercontinuum.

Nonlinear Applications using Silicon Nanophotonic Wires
… large characteristic time associated with the self-steepening effect and optical-shock formation. In Chapter 4, I present an experimental demonstration of an ultrafast cross-phase-modulation-based wavelength-conversion (XPM-WC) technique for telecom RZ-OOK data. I also investigate the effect of …

Optical frequency comb generation in optical fibres
… effect, the delayed Raman response, the pulse self-steepening, and the linear optical losses as well as the wavelength-dependent Erbium gain profile for the second fibre. The initial condition equation being a deeply-modulated cosine-wave mimics the radiation of the two initial CW lasers. The …

Hypersound interaction studied by time-resolved inelastic light and x-ray scattering
… similar to shallow water waves which show a steepening of wave fronts or solitons well known as tsunamis. Due to the high amplitude of the acoustic wave packets in the solid, the acoustic properties can change significantly in the vicinity of the sound pulse. This may lead to a shape change …
