The disclosure provides recording materials including thiophosphate 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 thiophosphate derivatized monomers and polymers for use in Bragg gratings applications, leading to materials with higher refractive index, low birefringence, and high transparency. The disclosed thiophosphate 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.
该披露提供了用于体积布拉格光栅的记录材料,包括硫代磷酸酯衍生单体和聚合物,用于全息应用的体积布拉格光栅,但不限于此。披露了几种用于布拉格光栅应用的硫代磷酸酯衍生单体和聚合物的结构,导致具有更高折射率、低双折射和高透明度的材料。披露的硫代磷酸酯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,其中矩阵在第一步固化,然后通过第二步单体的固化来编写体积布拉格光栅。
