  Existence of a new class of soliton solutions is shown for higher order
nonlinear Schrodinger equation, describing thrid order dispersion, Kerr effect
and stimulated Raman scattering. These new solutions have been obtaiened by
invoking a group of nonlinear transformations acting on localised stable
solutions. Stability of these solutions has been studied for different values
of the arbitrary coefficients, involved in the recursion relation and
consequently, different values of coefficient lead to different transmission
rates for almost same input power. Another series solution containing even
powers of localised stable solution is shown to exist for higher order
nonlinear Schrodinger equation.
