Surface Plasmons Enable Tunable Color Filters

  SINGAPORE, Aug. 30, 2012 — Combining a thin, perforated gold film with a liquid crystal layer makes a tunable, efficient color filter, engineers at A*STAR, the Agency for Science, Technology and Research in Singapore, report.

ZnO photonic-crystal laser emits in the UV

Although low-threshold lasing in the IR has been realized in photonic-­crystal slabs made of III-V semiconductor materials, a UV photonic-crystal laser represents a special challengebecause of the different materials and the smaller feature sizes required for the crystal.
