Stable dark solitons in PT-symmetric dual-core waveguides
Yuliy V. Bludov, Vladimir V. Konotop, Boris A. Malomed
We construct dark solitons in the recently introduced model of the nonlinear dual-core coupler with the mutually balanced gain and loss applied to the two cores, which is a realiza…
Modulation Instabilities in Birefringent Two-Core Optical Fibers
J. H. Li, K. S. Chiang, B. A. Malomed +1
Previous studies of the modulation instability (MI) of continuous waves (CWs) in a two-core fiber (TCF) did not consider effects caused by co-propagation of the two polarized modes…
Soliton trapping in multimode fibers with random mode coupling
Antonio Mecozzi, Cristian Antonelli, Mark Shtaif
We derive the fundamental equations describing nonlinear propagation in multi-mode fibers in the presence of random mode coupling within quasi-degenerate groups of modes. Our resul…
Nonlinear propagation in multi-mode fibers in the strong coupling regime
Antonio Mecozzi, Cristian Antonelli, Mark Shtaif
In spite of the massive interest that the generalized Manakov equation has attracted in the past two decades, no physical system which is quantitatively described by this equation…
