Patent ID: 6852358

Claim:
A process for preparing an optical waveguide component from acrylate/titanium alkoxide composite material, which comprises the following steps: (a) reacting acrylate with titanium alkoxide in the presence of silicon coupling agent and water by an acid-free solgel method to form a precursor solution of an acrylate/titanium alkoxide composite material; (b) coating the resultant precursor solution on a silicon chip on which a silicon dioxide has been previous coated, and then evaporating solvent from the solution at a temperature from 50 to 200° C. to form a acrylate/titanium alkoxide composite material film; (c) forming a channel on the resultant film by lithographic method; (d) repeating the step (a) except using a ratio of acrylate and titanium alkoxide different from that used in step (a) to form a precursor solution having a refractive index less than the precursor solution obtained from step (a); and (e) applying the precursor solution obtained in step (d) on the composite material film having channels in step (c), evaporating solvent at a temperature of from 70 to 90° C., and then baking at a temperature of from 50 to 200° C., to produce the optical waveguide component of acrylate/titanium alkoxide composite material.
