Optical channel waveguides have been obtained by electric-field-assisted diffusion of copper films on glass substrates. The mode indices of these channel waveguides were determined with the prism-coupling technique, and the refractive-index profile of the waveguide was reconstructed from measurements of the near-field intensity distribution.
