Study of the gain saturation effect on the propagation of dark soliton in Er super(+) 3-doped, Ga sub(5)Ge sub(20)Sb sub(10)S sub(65) chalcogenide fiber amplifier

We study the effect of gain saturation on the propagation of fundamental dark soliton in a nonlinear, dispersive and amplifying medium. The Er super(+) 3-doped, Ga sub(5)Ge sub(20)Sb sub(10)S sub(65) chalcogenide glass is used for dark and erbium doped silicon glass for bright solitons. The numerica...

Description
Summary:We study the effect of gain saturation on the propagation of fundamental dark soliton in a nonlinear, dispersive and amplifying medium. The Er super(+) 3-doped, Ga sub(5)Ge sub(20)Sb sub(10)S sub(65) chalcogenide glass is used for dark and erbium doped silicon glass for bright solitons. The numerical simulations show that dark soliton doesn't split to subpulses unlike bright soliton and also the dark soliton is more stable in the presence of gain saturation and gain dispersion effects. So the chalcogenide glasses are suitable for designing all optical devices.
