Gap solitons in Bragg gratings with a harmonic superlattice
K. Yagasaki, I. M. Merhasin, B. A. Malomed +2
Solitons are studied in a model of a fiber Bragg grating (BG) whose local reflectivity is subjected to periodic modulation. The superlattice opens an infinite number of new bandgap…

Gap solitons in a model of a hollow optical fiber
I. M. Merhasin, Boris A. Malomed
We introduce a models for two coupled waves propagating in a hollow-core fiber: a linear dispersionless core mode, and a dispersive nonlinear quasi-surface one. The linear coupling…
