The disclosure provides recording materials including mono- or poly-phenyl-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 mono- or poly-phenyl-core derivatized monomers and polymers for use in Bragg gratings applications, leading to materials with higher refractive index, low birefringence, and high transparency. The disclosed mono- or poly-phenyl-core 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.
本公开提供了用于体积布拉格光栅的单核苯基或多核苯基衍生单体和聚合物的记录材料,包括但不限于用于全息应用的体积布拉格光栅。公开了用于布拉格光栅应用的单核苯基或多核苯基衍生单体和聚合物的几种结构,导致具有更高的折射率,低双折射率和高透明度的材料。公开的单核苯基或多核苯基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,其中基质在第一步中固化,然后通过第二次单体固化步骤编写体积布拉格光栅。
