            Abstract : 
A multilayer graded-index fibre with a numerical aperture of 0.2 which shows low modal dispersion has been fabricated with the aid of the plasma activated c.v.d. process. At 905 nm, the f.w.h.m. modal broadening was found to be about 150 ps/km, obtained for full mode excitation.
