Summary form only given. We show the first depressed-core-index photonic-band-gap (DCI-PBG) fibre manufactured by means of the classical MCVD technique. It has been designed to propagate a robust zero dispersion single mode at wavelengths as short as 1 /spl mu/m. The main applications deal with non-linear optics: soliton propagation, parametric amplification and oscillators, this fibre consists in a low-index cylindrical core surrounded by a cladding made of layers with alternating high and low indices, which values are higher than that of the core. It has been theoretically demonstrated in a previous paper that such a fibre can propagate one single guided mode. We have designed the DCI-PBG fibre for simultaneously obtaining a suitable coupling to standard fibres and achieving a zero dispersion at /spl lambda//sub 0/=1.06 /spl mu/m by the aim of a two dimensions scalar cylindrical finite-difference beam propagation method (2D FD-BPM) associated to the Wijnand's method. The chromatic dispersion of the guided mode is presented at the conference.
