    • The invention provides a method for producing an optical waveguide that includes the steps of: (a) forming a core structure, the core structure including an at least partially cured core composition, on a master defining a waveguide pattern; (b) applying over the top of the core structure and the master a cladding layer including a liquid cladding composition; (c) curing the cladding layer to form a core/cladding combination; and removing the core/cladding combination from the master so as to expose at least a portion of the core structure, wherein the refractive index of the core material is at least about 0.05 percent higher than the refractive index of the cladding material. In another embodiment, the invention relates to a method for producing an optical waveguide core structure that includes the steps of: (a) applying a core composition to a substrate defining a waveguide core pattern; (b) removing a portion of the core composition from an exposed surface of the filled waveguide core pattern; and (c) at least partially curing the core composition to form a core structure. In another embodiment, the invention relates to a composition for forming either the core or cladding portion of an optical waveguide comprising at least one norbornene-type monomer and/or at least one crosslinking monomer and at least one co-catalyst or procatalyst, wherein polymerization is achieved by the addition of at least one procatalyst (when a co-catalyst is present in the composition) or at least one cocatalyst (when a pro-catalyst is present in the composition). Optical waveguides made by the methods of the invention are also disclosed.
    • 本发明提供了一种制造光波导的方法,包括以下步骤:(a)在限定波导图案的母板上形成芯结构,芯结构包括至少部分固化的芯组合物; (b)在芯结构的顶部和主体上施加包括液体包层组合物的包层; (c)固化包覆层以形成芯/包层组合; 以及从所述主体移除所述芯/包层组合以暴露所述芯结构的至少一部分,其中所述芯材料的折射率比所述包层材料的折射率高至少约0.05%。 在另一个实施例中,本发明涉及一种用于制造光波导芯结构的方法,其包括以下步骤:(a)将芯组合物施加到限定波导芯图案的衬底上; (b)从所述填充的波导芯图案的暴露表面去除所述芯组合物的一部分; 和(c)至少部分固化所述芯组合物以形成芯结构。 在另一个实施方案中,本发明涉及用于形成光波导的芯或包层部分的组合物,其包括至少一种降冰片烯型单体和/或至少一种交联单体和至少一种助催化剂或前催化剂,其中聚合 通过加入至少一种前催化剂(当组合物中存在助催化剂时)或至少一种助催化剂(当组合物中存在促催化剂时)。 还公开了通过本发明的方法制造的光波导。
