The disclosure provides recording materials including aromatic substituted methane-core derivatized monomers and polymers for use in volume Bragg gratings, including, but not limited to, volume Bragg gratings for holography applications. Several structures are disclosed for monomers and polymers for use in Bragg gratings applications leading to materials with higher refractive index, low birefringence, and high transparency. The disclosed derivatized monomers and polymers thereof can be used in any volume Bragg gratings materials, including two-stage polymer materials where a matrix is cured in a first step, and then the volume Bragg grating is written by way of a second curing step of a monomer.
披露提供了包括芳香取代
甲烷核衍生单体和聚合物在内的记录材料,用于体积布拉格光栅,包括但不限于用于全息应用的体积布拉格光栅。披露了用于布拉格光栅应用的单体和聚合物的几种结构,导致具有较高折射率、低双折射和高透明度的材料。披露的衍生单体和聚合物可以用于任何体积布拉格光栅材料,包括两阶段聚合物材料,其中矩阵在第一步中固化,然后通过单体的第二次固化步骤编写布拉格光栅。
