The extraordinary optical transmission (EOT) and diffraction through nanoslit composed of two finite-width metallic films with periodic or aperiodic sub-wavelength corrugation were studied. The transmitted spectra were calculated and compared, and the numerical results showed that two transmission peaks exist for the periodic corrugation, while for aperiodic one the transmission peaks are split into seven, corresponding to their different periods and couplings. Further investigation indicated that resonant wavelength of Surface Plasmon Polaritons (SPPs) determined by the nanoslit can be distinguished. It is expected that this investigation will provide useful information for further designing various nano-scaled optical filters and wavelength division multiplexer (WDM) in the next all optical network (AON).

AbstractHow to capture electromagnetic fields into sub-wavelength spatial scales has been a major challenge in nanophotonics, especially confining surface plasmon polaritons into regions as small as a few nanometers. Although various methods are proposed to achieve this goal, these methods require complex fabrication process. Here, we demonstrate experimentally the achievement of nanofocusing of surface plasmon polaritons with an intensity enhancement of three, using the simple structure with just pasting a sliver microwire on a sliver layer. And the designed structure has a well-defined gravitational field inspired by transformation optics. This simple design structure has applications to enhance light–matter interactions, such as nonlinear optical process and Raman scattering.

AbstractPlasmonics is a rapidly expanding field, founded in physics but now with a growing number of applications in biology (biosensing), nanophotonics, photovoltaics, optical engineering and advanced information technology. Appearing as charge density oscillations along a metal surface, excited by electromagnetic radiation (e.g., light), plasmons can propagate as surface plasmon polaritons, or can be confined as standing waves along an appropriately-prepared surface. Here, we review the latter manifestation, both their origins and the manners in which they are detected, the latter dominated by near field scanning optical microscopy (NSOM/SNOM). We include discussion of the “plasmonic halo” effect recently observed by the authors, wherein cavity-confined plasmons are able to modulate optical transmission through step-gap nanostructures, yielding a novel form of color (wavelength) selection.
