Stabilizing soliton-based multichannel transmission with frequency dependent linear gain-loss

 http://repository.vnu.edu.vn/handle/VNU_123/27245

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. 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
