We present a study about a photonic crystal fibre whose strands are filled by defocusing nonlinear medium. The strength of defocusing nonlinearity grows towards the periphery of the fibre. The nonlinearity considered of uniform defocusing type and for a nonzero growth rate of defocusing nonlinearity also considered separately. We have obtained that stable bright and vortex soliton exist in PCF infiltrated with an inhomogeneous defocusing nonlinearity without any modulation of linear refractive index and it is self sustained too.
