Surface-plasmon-polariton-induced suppressed transmission through ultrathin metal disk arrays.
نویسندگان
چکیده
We report surface-plasmon-polariton-induced suppressed transmission through two-dimensional arrays of isolated metal disks with a thickness comparable to optical skin depth of the metal. A transmittance dip of -17.5 dB is achieved at the resonant wavelength of 1524 nm, compared to -12 dB for closed film. Coupling the light into the surface-plasmon polariton results in enhanced absorption, which is potentially interesting in solar cell applications.

Dual effect of surface plasmons in the light transmission through perforated metal films
The light transmission through perforated metal film has been studied both experimentally and theoretically. By taking account of plasma response of real metal on hole walls as well as metal surface, an analytical result for the transmission has been deduced, which agrees well with the experiments. The transmission involves both the diffraction modes and the surface plasmons. The surface plasmo...
متن کاملLocalised modes of sub-wavelength hole arrays in thin metal films
When perforated metal films are sufficiently thin, in addition to exciting surface plasmon-polariton (SPP) modes by conventional two dimensional grating scattering, there is also the possibility of coupling to the localised modes associated with the holes. Here, experimental transmission spectra are obtained from focused ion beam fabricated hole arrays exhibiting localized modes in the visible ...
متن کاملObservation of coupled plasmon-polariton modes of plasmon waveguides for electromagnetic energy transport below the diffraction limit
We study the influence of optical near-field interactions on the dipole surface plasmon resonance of Au nanoparticles in closely spaced particle arrays using finite-difference timedomain simulations. In particular, the resonance energies of the collective plasmon-polariton modes are determined for longitudinal and transverse polarization for different particle array lengths and inter-particle s...
متن کاملCoupling, resonance transmission, and tunneling of surface-plasmon polaritons through metallic gratings of finite length.
The Green’s-theorem integral equation formulation is employed to study numerically the coupling into surface plasmon polaritons by illuminating a finite metal grating with a Gaussian beam from the vacuum half-space above the metal surface. A flat surface impedance boundary condition is used to simplify the scattering integral equations. The grating coupler period is chosen so that the first dif...
متن کاملTransmission of light through thin silver films via surface plasmon-polaritons.
We report results of measurements and calculations that help to clarify the role of surface plasmon-polariton modes in the transmission of light through thin continuous films of silver. Our experimental data show that there is an optimum silver film thickness for which transmission is maximal. We offer an explanation of this phenomenon in terms of competition between increasing absorption in th...
