The synthesis of novel, high μβ electro-optical chromophores is described. These chromophores are polymerizable with a host polymer or copolymer. The chromophore polymerizable groups comprise epoxy, thioepoxy, oxetane and thiooxetane material which undergo a ring opening polymerization reaction in the presence of a cationic photoinitiator and actinic radiation. The high μβ chromophores, mixed with a selected host polymer, copolymer, oligomer, or one or a plurality of polymerizable monomers, can be used to prepare optical waveguides and other optical elements and/or devices. The electro-optical chromophores of the invention can be used as a replacement for LiNbO3 in the formation of electro-optical devices, particularly electro-optical modulators.
