HIGH POLYMER OPTICAL WAVEGUIDE AND ITS MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To provide an optical waveguide which uses a benzoxazole copolymer whose refractive index and birefringence are precisely controlled, and its manufacturing method. SOLUTION: This high polymer optical waveguide is characterized in that the benzoxazole copolymer containing at least one of recurring units represented by a structural formula (1) and recurring units represented by a structural formula (2) is used for at least one of the core and clad.
