PRODUCTION OF WAVEGUIDE DEVICE

摘要

The specification describes a process for forming an organic optical waveguide device of predetermined planar geometry. First a layer of an organic photoactive composition is deposited to a predetermined thickness on a given substrate. The photoactive composition is characterized by being capable of forming a waveguiding material upon polymerization or depolymerization. Next, the deposited photoactive layer is exposed to a beam of ultraviolet radiation through a mask which defines the desired planar geometry for the device to be formed. Finally, the exposed photoactive layer is developed to remove undesired portions thereof and to leave an organic waveguiding portion having the predetermined planar geometry. The photoactive composition may be positive or negative working.
