Paper Abstract

Waveguides have been fabricated by a hybrid organic- inorganic glass sol-gel process and ultraviolet-light exposure. The adjustment of chemical composition of the materials provides precise selection of the refractive index from 1.48 to 1.52 at the wavelength of 632.8 nm. The effect of ultraviolet-light exposure and heat treatment on the refractive index is studied. Ultraviolet-light inscription has been employed to produce ridge waveguides with smooth sidewalls.
