We
report several major theoretical steps towards realizing stable long-distance
multichannel soliton transmission in Kerr nonlinear waveguide loops.
We
find that transmission destabilization in a single waveguide is caused by
resonant formation of radiative sidebands and investigate the possibility to
in-crease transmission stability by optimization with respect to the Kerr
nonlinearity coefficientγ.
More-over,
we develop a general method for transmission stabilization, based on frequency
dependent linear gain–loss in Kerr nonlinear waveguide couplers, and implement
it in two-channel and three-channel transmission.
We
show that the introduction of frequency dependent loss leads to significant
en-hancement of transmission stability even for non-optimalγvalues via decay of
radiative sidebands, which takes place as a dynamic phase transition.
For
waveguide couplers with frequency dependent linear gain–loss, we observe stable
oscillations of soliton amplitudes due to decay and regeneration of the
radiative sidebands

| Abstract: | We report several major theoretical steps towards realizing stable long-distance multichannel soliton transmission in Kerr nonlinear waveguide loops. We find that transmission destabilization in a single waveguide is caused by resonant formation of radiative sidebands and investigate the possibility to in-crease transmission stability by optimization with respect to the Kerr nonlinearity coefficientγ. More-over, we develop a general method for transmission stabilization, based on frequency dependent linear gain–loss in Kerr nonlinear waveguide couplers, and implement it in two-channel and three-channel transmission.
