Nn. Akhmediev et Av. Buryak, SOLITON STATES AND BIFURCATIONS IN PERIODICALLY TWISTED BIREFRINGENT FIBER FILTERS, Optics communications, 113(4-6), 1995, pp. 505-508
We study analytically and numerically coupled soliton states in period
ically twisted birefringent optical fibers. The bifurcation diagram fo
r the lowest order soliton states is constructed in the cases of zero
and nonzero detunings from the phase-matching conditions.
