Stability of data storage is essential for optical information processing. TiO_2 nanoporous
films loaded with small-sized Ag nanoparticles thus attracted much attention due to their fast …

This study introduces a method for visualizing holes automatically utilizing ultrasonic
wavefield pictures acquired by a noncontact laser scanning device. Hidden holes and leaks …

Tunable waveguide Bragg gratings were demonstrated in PYR-3 chromophore doped
polymers. We report on the fabrication and the performance of the device. Polycarbonate …
