The optical article of the invention, e.g., holographic recording medium or polymeric waveguide, is formed by mixing a matrix precursor and a photoactive monomer, and curing the mixture to form the matrix in situ. The reaction by which the matrix precursor is polymerized during the cure is independent from the reaction by which the photoactive monomer is polymerized during writing of data. In addition, the matrix polymer and the polymer resulting from polymerization of the photoactive monomer are compatible with each other. Use of a matrix precursor and photoactive monomer that polymerize by independent reactions substantially prevents cross-reaction between the photoactive monomer and the matrix precursor during the cure and inhibition of subsequent monomer polymerization. Use of a matrix precursor and photoactive monomer that result in compatible polymers substantially avoids phase separation. And in situ formation allows fabrication of articles with desirable thicknesses.
本发明的光学产品,例如全息记录介质或聚合物波导,是通过混合基质前体和光活性单体,并固化混合物以在原位形成基质而形成的。基质前体在固化过程中的聚合反应与光活性单体在写入数据过程中的聚合反应无关。此外,基质聚合物和光活性单体聚合产生的聚合物是相互兼容的。使用通过独立反应聚合的基质前体和光活性单体,可有效防止光活性单体和基质前体在固化过程中发生交叉反应,并抑制后续单体聚合。使用可产生相容聚合物的基质前体和光活性单体,可有效避免相分离。原位形成可制造出具有理想厚度的产品。
