The present invention relates to a process for preparing an optical
waveguide component from acrylate/titanium alkoxide composite material,
which is characterized by using an acid-free sol-gel process to prepare a
precursor solution of acrylate/titanium alkoxide composite film, then
coating the precursor solution on a silicon wafer then drying, and
producing the optical waveguide component having channels by using a
lithography process. The present invention also relates to an optical
waveguide component of acrylate/titanium alkoxide composite material, the
material has excellent transparency and its refractive index varies with
the amount of titanium alkoxide contained therein. When an optical
waveguide component is prepared from the composite the reduction of
near-infrared ray is less than 0.7 dB/cm and therefore the waveguide
component is advantageous for use as an optical communication element.
