Self-written waveguide in methylene blue sensitized poly(vinyl alcohol)/acrylamide photopolymer material

We report the observation of a self-written waveguide inside a bulk methylene blue sensitized poly/vinyl alcohol)/acrylamide photopolymer material. Light from a low power He-Ne laser is focused into the material, and the evolution of the beam is monitored. The refractive index of the material is mod...
