Mohammed Nadhim Abbas, Ahmed Abdulredha Ali . An Efficient Four Channels 3D Plasmonic Demultiplexer. International Journal of Computer Applications. 130, 9 ( November 2015), 37-41. DOI=10.5120/ijca2015907116
Abstract
The four channels of 3D plasmonic demultiplexer structure are selective based, on a nanocavity, that proposed, and numerically simulated, by using the finite, element method by using COMSOL4.4 software package The required, filtered wavelength can, be investigated, by selecting, an appropriate length of, the nanocavity and refractive index of dielectric that filled nanocavity. The selecting wavelength of for 3D channels are dependent on three geometric parameters thickness , width and length. Four, output channels, structure based, on four perpendicular, nanocavities that, proposed to, design a subwavelength, plasmonic splitter, and demultiplexer. 3D plasmonic demultiplexer with 1× 4 channels it's peak transmisson of four channels occurs at around the wavelengths of 810nm, 990nm, 1210nm and 1500nm ,with transmittance effeceincy are 57% , 72%, 74%, 70% respectively.Three materials used to build structure ,metal used as a silver and two types of dielectric quartz with refractive index 1.5 and air with refractive index 1."
