“…We have also studied the interplay between SRS and pumpcavity de-synchronization, obtaining strong evidence that asymmetric soliton steps observed in recent experiments arise precisely due to such interplay. Our findings shed light on the dynamics of CSs in the presence of pulsed driving fields, and could have impact on the design of efficient microresonator frequency combs [12,28] or freespace enhancement cavities [42].…”

“…In addition to elucidating the dynamics of CSs under conditions of localized driving fields, our work could have impact on the design of efficient Kerr comb systems [12,28]. Our findings may also be relevant to other Kerr resonator systems where pulsed driving is used to support CSs, such as fiber ring resonators [15,19,24] or free-space enhancement cavities [42].…”

Impact of desynchronization and drift on soliton-based Kerr frequency combs in the presence of pulsed driving fields

et al. 2019

Pulsed driving of Kerr microresonators represents a promising avenue for the efficient generation of soliton states associated with coherent optical frequency combs. The underlying physics has not, however, yet been comprehensively investigated. Here, we report on a numerical and theoretical study of the impact of de-synchronization between the periodic pump field and the train of solitons circulating in the cavity. We show that de-synchronization can affect the soliton configurations that can be sustained for given parameters, and that it can be leveraged to guarantee operation in the attractive single-soliton regime. We also reveal that the interplay between pump-resonator de-synchronization and stimulated Raman scattering can give rise to rich dynamics that explain salient features observed in recent experiments. Our work elucidates the dynamics of Kerr cavity solitons in the presence of pulsed driving fields, and could facilitate the development of efficient microresonator frequency comb systems. arXiv:1905.09810v1 [physics.optics]

“…The electromagnetic field can alter the refraction index of the medium while propagating, thus establishing an architecture identical to a graded-index fiber [6][7][8][9][10]. • Temporal solitons: if the electromagnetic field is already spatially restricted, it is feasible to transmit pulses that will not alter their form, as the non-linear impacts will be in equilibrium with the dispersion [11][12][13][14][15].…”

Approximate Simulations for the Non-linear Long-Short Wave Interaction System

et al. 2020

This research paper studies the semi-analytical and numerical solutions of the non-linear long-short wave interaction system. This represents an optical field that does not change through multiplication due to a sensitive balance being struck between linear and non-linear impacts in an elastic medium, defined as a medium that can adjust its shape as a consequence of deforming stress and return to its original form when the force is eliminated. In this medium, a wave is produced by vibrations that are a consequence of acoustic power, known as a sound wave or acoustic wave. The Adomian decomposition method and the cubic and septic B-spline methods are applied to the suggested system to obtain distinct types of solutions that are used to explain the novel physical properties of this system. These novel features are described by different types of figures that show more of the physical properties of this model. Also, the convergence between the obtained solutions is discussed through tables that show the values of absolute error between them.

“…Accelerating the gas to provide (nearly) single-pass conditions even at several tens of MHz has been shown to strongly mitigate the latter limitation, resulting in mW-level VUV frequency combs [13]. In addition, novel, nonlinearity-optimized ultrashort-pulse enhancement regimes [12,15] promise a path to circumvent the blueshift-related intensity clamping [10][11][12]. Altogether, these recent advances indicate a vast potential of improving the intracavity conversion efficiency.…”

Cavity-enhanced noncollinear high-harmonic generation

et al. 2019

View full text Add to dashboard Cite

Femtosecond enhancement cavities have enabled multi-10-MHz-repetition-rate coherent extreme ultraviolet (XUV) sources with photon energies exceeding 100 eV-albeit with rather severe limitations of the net conversion efficiency and of the duration of the XUV emission. Here, we explore the possibility of circumventing both these limitations by harnessing spatiotemporal couplings in the driving field, similar to the "attosecond lighthouse," in theory and experiment. Our results predict dramatically improved output coupling efficiencies and efficient generation of isolated XUV attosecond pulses.
