New Experimental-Technique For The Fabrication Of Ion Diffused Optical-Glass Wave-Guides

A new electric-field-assisted ion diffusion technique has been used for the fabrication of optical waveguides in glass. The construction of the setup is discussed in detail. Ion exchange in standard glass slide can be performed very efficiently and the setup can be conveniently used for double diffusions which are required for the fabrication of buried waveguides. Silver ions of various mole fractions were diffused in glass by this technique. Diffusion depth measurements were made both for the fabricated planar and channel waveguides
