Abstract
We report an experimental investigation of the nonlinear refractive in dex change of a highly ytterbium-doped silica slab waveguide. It is fo und that a negative index change of 2 x 10(-4) can be obtained at pump power of 350 mW and it is predicted that this could be reduced to abo ut 30 mW by optimizing the experimental conditions.
