Asymptotic series for the square of modal propagation constants of a general class of graded index refractive index profiles are investigated to including 0( k −8 ) using nonlinear transforms of order one, two and three. Here, the behaviour of spatial transients is considered. Description in terms of transforms of order one and two is locally compared to the third order description. The local sequence‐behaviour is reflected in the results presented.
