Abstract

The comparison between the NCTU and Caltech PQ-PMMA material shows that the difference in their behavior lies in the different concentration of residual MMA in the samples. Experimental evidence shows that during recording, PQ molecules attach to MMA but no diffusion takes place at room temperature. However, the excess of monomer during recording enables photoinduced polymerization as a mechanism for hologram formation leading to high diffraction efficiencies without the need of baking. The grating formed by the PQ-MMA groups is unstable and it can be erased within a few hours of baking.
