Abstract
An optical polymer composition in which polymers having the same repeating units with different polymerization ratios are mixed in an arbitrary ratio. An optical material having a desired refractive index can be attained by appropriately adjusting the mixing ratio based on weight. With such a composition, it is easy to finely adjust the difference in refractive indices between a core and a cladding forming an optical waveguide, thus an optical waveguide device can be easily fabricated.
