Abstract
The specification describes a process for forming an organic optical waveguide device of predetermined planar geometry. First a layer of an organic photoactive composition (for example, phenylglyoxylic acid or a derivative thereof) 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. 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 leave behind a portion of the photoactive material which has the desired planar geometry and which is an organic waveguiding material.
