Efficient Photo-Response of Azobenzene-based Compounds for Holographic Recording
One of the challenges for azobenzene-based materials in fabricating rewritable surface relief gratings is the long response time in the procedure of holographic recording, making it inefficient in real-time applications.

Surface-relief and polarization gratings for solar concentrators
Transmission gratings that combine a large diffraction angle with a high diffraction efficiency and a low angular and wavelength dispersion could be used to collect sunlight in a light guide. In this paper we compare the diffractive properties of polarization gratings and classical surface-relief gratings and explore their possible use in solar ...

Surface-relief polarization gratings for visible light
Polarization gratings are space-variant subwavelength-structured photonic devices that control electromagnetic wave propagation by local modulation of the state of polarization of light. Using electron beam lithography, we have fabricated such devices in the form of dielectric and metallic surface-relief profiles for operation in the visible wavelength
