We investigated the microstuctural properties, as well as the linear and the nonlinear optical properties of silver nanoparticles embedded within a polymer matrix. The monolayered silver nanoparticles were fabricated by using a thermal treatment of t

We investigated the photo-structuring of silver-oxide lms by using femtosecond laser pulses. The silver-oxide lms were prepared by magnetron sputtering. The physical properties of the prepared silver-oxide lms were investigated by using absorption sp

We design and fabricate a novel tunable wavelength filter, which utilizes long-range surface plasmon-polaritons excited along nm-thick-metal strips. A gold metal strip, with cm length, 20 nm thickness, and 5m width, is embedded in thick thermo-optic

Extraordinary phenomena related to the transmission of light via metallic films with subwavelength holes and grooves are known to be due to resonant excitation and interference of surface waves. These waves make various surface structures to have opt

Photonic band gaps created by Bragg scattering of the surface plasmon polaritons are observed from dielectric grating structures on a flat metal surface. Observation results that directly image the band gaps are confirmed by the well-known numerical

For dielectric gratings on a flat metal surface, photonic band gaps created by Brags scattering of surface plasmon polaritons are observed. The observation result that directly images this gap is compared with that predicted by a numerical model base

We have observed experimentally photonic band gap in dispersion curves of SPPs excited at a 1-D dielectric lattice structure on a flat metal surface. The observation result is compared with theoretical result by using of the well-known calculation me
