Optical waveguide made of polymer material and a method of fabricating the same |
摘要 |
An optical waveguide having a clad and a core, the core being made of polymer material containing a repetitive unit having formula (1), (2) or (3): Each of these polymer materials has a higher glass transition temperature and lower water absorption than those of deuterated PMMA, has a transparency equivalent with that of deuterated PMMA, and shows neither light absorption nor scattering in the operating wavelength region. An optical waveguide with a core fabricated using these polymer materials is high in heat resistance and low in water absorption. Thus using the waveguide will successfully provide optical communication elements with an advanced durability against the environment.
