Propagation of an optical pulse in a fiber link with random dispersion management
Anders Berntson, Boris A. Malomed
A model of a long optical communication line consisting of alternating segments with anomalous and normal dispersion, whose lengths are picked up randomly from a certain interval,…
Helical vs. fundamental solitons in optical fibers
Boris Malomed, G. D. Peng, P. L. Chu
We consider solitons in a nonlinear optical fiber with a single polarization in a region of parameters where it carries exactly two distinct modes, the fundamental one and the firs…
Split-step solitons
Rodislav Driben, Boris A. Malomed
We consider a long fiber-optical link consisting of alternating dispersive and nonlinear segments, i.e., a split-step model (SSM), in which the dispersion and nonlinearity are comp…
Propagation and interaction of ultrashort electromagnetic pulses in nonlinear media with a quadratic-cubic nonlinearity
Elena Kazantseva, Andrey Maimistov, Boris Malomed
Propagation of extremely short unipolar pulses of electromagnetic field ("videopulses") is considered in the framework of a model in which the material medium is represented by anh…
Structure of binary Bose-Einstein condensates
M. Trippenbach, K. Goral, K. Rzazewski +2
We identify all possible classes of solutions for two-component Bose-Einstein condensates (BECs) within the Thomas-Fermi (TF) approximation, and check these results against numeric…
Bragg-grating solitons in a semilinear dual-core system
Javid Atai, Boris A. Malomed
We investigate the existence and stability of gap solitons in a double-core optical fiber, where one core has the Kerr nonlinearity and the other one is linear, with the Bragg grat…
