title: Optical channel waveguides by copper ion-exchange in glass.
abstract: 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.
