ABSTRACT:
Optical waveguides comprise as core and cladding materials a chemical compound in two different crystalline forms with different indices of refraction. Preferably, the non-linear form is anhydrous and the linear form is a hydrate thereof, whereupon the core material can be prepared by selective heating of the cladding material as by a laser beam. A preferred compound is 4'-dimethylamino-4-methylstilbazolium p-toluenesulfonate.
