Diblock copolymers composed of a side-chain liquid crystalline azobenzene-containing
polymethacrylate and poly (tert-butyl acrylate)(PAzoMA-bP t BA) were prepared using atom …

Two diblock copolymers composed of polystyrene and a liquid crystalline azobenzene-
containing polymethacrylate were used as model systems to investigate the confinement …

Holographic volume index gratings with high diffraction efficiency (greater than 80%) are
recorded in a thick sample of Disperse Red 1–doped poly (methyl methacrylate) with red …

To study the origin of reversible holographic recording in three polymers containing the
same azo-dye, we have measured the diffraction efficiency and analyzed the gratings …

We give an overview of our recent work on improving the optical performance of polymeric
materials via supramolecular concepts, ie, by making use of spontaneous non-covalent …

To optimize azobenzene-containing materials for applications such as rewritable
waveguides and holographic data storage, it is imperative to understand the effect of the …

This work explores the use of photoactive elastomers as elastic holographic materials.
Holographic gratings were recorded on stretched films of an azobenzene elastomer, which …

Optical birefringence in polymeric films containing azo-chromophores is an important feature
related to the development of several technologies such as electro-optic modulators, optical …

Photo-induced birefringence has been measured by a pump–probe experiment in pure
silica and ORMOSILs (ORganically MOdified SILanes) thin films containing Disperse Red 1 …

We have developed an azo-dye-doped acrylate-based material formulation for holographic
lithography. Volume phase gratings and two-dimensional photonic crystals were …
