Paper Abstract

The refractive index of Germanium-doped planar waveguides can be changed when it is exposed to UV light. Furthermore, if the waveguide is bombarded by ions during exposure, a negative index change is obtained. If the waveguide is not bombarded by ions, positive change in index results. In a dye-doped polymer fiber, large index change is obtained due to the photosensitivity effect of the dye, in our case, fluorescein. However, the basic material, PMMA, is also photosensitive.
