    摘要： The present invention relates to a system, as well as articles and holographic recording medium comprising the system, where the system comprises: a polymerizable component comprising at least one photoactive polymerizable material; and a photoinitiator component comprising at least one photoinitiator for causing the polymerizable component to polymerize to thereby form a plurality of holographic gratings when activated by exposure to a photoinitiating light source; wherein when a portion of the polymerizable component has been polymerized to form at least one holographic grating, the unpolymerized portion of the polymerizable component is resistant to further polymerization when not exposed to the photoinitiating light source. The present invention also provides methods for forming at least one holographic grating in a holographic recording medium having such a photopolymerizable system.

    摘要： An optical medium is provided. The optical medium comprises: a diffusion-controlling matrix framework; at least one photoactive monomer attached to the diffusion-controlling matrix framework in a first state of the optical medium, wherein the at least one photoactive monomer is released from the diffusion-controlling matrix framework by photo cleavage, producing a second state of the optical medium, in which diffusion of the photoactive monomer through the optical medium is possible; and wherein the at least one photoactive monomer is then polymerized or reattached to the diffusion-controlling matrix, giving a third state of the optical medium, when exposed to photo-polymerizing light.
