Abstract
A fluorinated polymerizable compound useful for fabricating planar optical devices includes at least one fluorinated alkylene or alkylene ether moiety and at least two terminal acrylate moieties, each terminal acrylate moiety being connected to one of the fluorinated alkylene or fluorinated alklene ether moieties by an ester linking group. The fluorinated polymerizable compounds, or macromers, of this invention are useful for forming optical components exhibiting a refractive index comparable to that of glass fiber waveguides, while also exhibiting very low absorption losses. Polymerizable compositions suitable for preparing optical components can be prepared by combining the macromers of the invention with a photoinitiator. Conventional optical monomers may also be employed, if desired.
