“…Recently Kim et al (2015) proposed that by mixing gases one could independently control the Kerr and ionization based nonlinearities, using a mixture of two gases with significantly different ionization potentials. In this way one gas maintains the Kerr-driven soliton dynamics, while the other gives rise to a separately controllable blueshift.…”

This article offers an extensive survey of results obtained using hybrid photonic-crystal fibers (PCFs) which constitute one of the most active research fields in contemporary fiber optics. The ability to integrate novel and functional materials in solid-and hollow-core PCFs through various postprocessing methods has enabled new directions toward understanding fundamental linear and nonlinear phenomena as well as novel application aspects, within the fields of optoelectronics, material and laser science, remote sensing, and spectroscopy. Here the recent progress in the field of hybrid PCFs is reviewed from scientific and technological perspectives, focusing on how different fluids, solids, and gases can significantly extend the functionality of PCFs. The first part of this review discusses the efforts to develop tunable linear and nonlinear fiber-optic devices using PCFs infiltrated with various liquids, glasses, semiconductors, and metals. The second part concentrates on recent and state-of-the-art advances in the field of gas-filled hollow-core PCFs. Extreme ultrafast gas-based nonlinear optics toward light generation in the extreme wavelength regions of vacuum ultraviolet, pulse propagation, and compression dynamics in both atomic and molecular gases, and novel solitonplasma interactions are reviewed. A discussion of future prospects and directions is also included.

“…The concept of optical solitons has played an important role in the development of nonlinear optics in recent years. Several remarkable applications of the use of solitons should be noted: supercontinuum generation [5][6][7][8]; self-compression of laser pulses to a duration of a small number of field oscillations [1,5,[9][10][11][12]; creation of effective sources of laser pulses in insufficiently developed spectral ranges, such as mid-IR [5,[13][14][15] and ultraviolet [16][17][18][19] through the use of various types of non-stationary nonlinearities (Raman and ionization ones).…”

An equation is derived for analyzing the self-action of a wave packets with few optical cycles in multicore fibers (MCF). A new class of stable out-of-phase spatio-temporal solitons with few cycle durations in the MCF with cores located in a ring is found and analyzed. The stability boundary of the obtained solutions is determined. As an example of using such solitons, we considered the problem of their self-compression in the process of multisoliton dynamics in the MCF. The formation of laser pulses with a duration of few optical cycles at the output of a ten-core MCF is shown.

Key words High-intensity lasers, ultra-short pulses, relativistic nonlinearity, self-focusing in plasma, selfcompression in plasma.The weakly relativistic regime of propagation of a short and intense laser pulse in the magnetized plasma is investigated. By considering relativistic nonlinearity and using non-linear Schrödinger equation with paraxial approximation, two second-order coupled differential equations are obtained for the longitudinal pulse width parameter (in time) and for the transverse pulse width parameter (in space). The simultaneous evolution of spot size and length of a relativistic Gaussian laser pulse in a magnetized plasma can be calculated by the numerical solution of the equations. The effect of magnetic field is investigated. It is observed that in the presence of magnetic field both the self-compression and the self-focusing can be enhanced. Furthermore, the interplay between the longitudinal self-compression and the transverse self-focusing in a magnetized plasma is investigated.
