Abstract
It is shown that dark solitons display an inherent instability for a s trong saturation of the nonlinear refractive index provided that the b ackground intensity exceeds a certain critical value. Such an instabil ity manifests itself as a drift of a black soliton that transform into a gray soliton and radiation. (C) 1996 Optical Society of America
