Reduction of Optical Bleaching Time in Optical Nonlinear Polymer Thin Films by Photosensitive Agent

摘要

The present invention relates to a method for shortening the optical turnaround time of an optical nonlinear polymer by adding a photosensitizer.;The present invention relates to a method of forming a nonlinear polymer thin film (4) containing a photosensitizer by uniformly mixing a polymer solution with a photosensitizer on a substrate (1), spin coating the same, and forming a mask (5) on the thin film After covering, it irradiates ultraviolet rays and causes the photobase reaction to occur quickly.;Therefore, the optical waveguide process of the present invention shortens the time required for fabricating the optical waveguide device, and has the effect that the waveguide fabrication takes place in a short time as a contact aligner.
