The propagation of laser pulses in multi-core fibers (MCF) made of a central core and an even number of cores located in a ring around it is studied. Approximate quasi-soliton homogeneous solutions of the wave field in the considered MCF are found. The stability of the in-phase soliton distribution is shown analytically and numerically. At low energies, its wave field is distributed over all MCF cores and has a duration, which exceeds the duration of the NSE soliton with the same energy by many…

Coherent propagation and amplification of intense laser pulses in hexagonal multicore fibers.
TLDR
Exact stable analytical solutions are found for the out-of-phase mode, which describes the coherent propagation of wave beams and temporal soliton solutions in fibers of 24 weakly coupled cores arranged in the form of seven close-packed hexagons.
Angular momentum supercontinuum from fibre rings
Broadband, coherent light carrying optical angular momentum (AM) is of potential utility for a variety of classical and quantum communication applications, but at present few such sources exist. We

We propose a method of laser pulse self-compression in an array of equidistant, identical, weakly-coupled active light guides. It is shown that laser pulse self-focusing in such one-dimensional

TLDR
It is shown that the pulses initially injected into all of the cores of a ring MCF are combined by nonlinearity into a small number of cores with simultaneous pulse compression.
