We confirmed that an optical frequency-modulated signal can be transmitted through surface plasmon polaritons (SPPs) in a sample consisting of a gold film with a light/SPP coupler (coupling and decoupling gratings).
We report an independently-addressed micro tunable cat's eye retro-reflector array. The device aims at serving as the ID tag in an optical identification system, hopefully a superior alternative to the current RFID systems. Dynamic images have been successfully generated by the tunable cat's eye array.
We coated a MEMS-based silicon optic with iridium by means of atomic layer deposition. Its X-ray reflectivity is quantitatively measured using a parallel X-ray beam at Al Kα 1.49 keV.
We present simulations showing how light scattered by isolated particles increases by a factor 10, when they are placed in photonic crystal membranes. Exploiting this effect, single nano-particles have been detected with an optical microscope.
