In this paper, we have proposed two novel plasmonic demultiplexing structures based on metal-insulator-metal surfaces which, beside their compact size, have a very good transmission spectrum. The impact of the key internal parameters on the transmission spectrum is numerically analyzed by using the twodimensional (2D) finite difference time domain (FDTD) method. The proposed structures could be...

Objectives. One of the topical tasks in development radio electronic systems for various purposes is a sharp increase volume and data transfer rate between elements system. This problem most successfully solved using fiber optic technology, which has no alternative to meet number indicators. The use optical fibers (OF) as physical medium made it possible large information flows over considerabl...

A digital system performs microoperations. The most well known digital system example is is a microprocessor. A microprocessor performs microoperations to run machine language instructions. Microoperations are simple operations that can be completed in one clock period, such as additions, subtractions, AND, OR, INVERT, compare, shift, rotate, read from memory, write to memory. Digital systems c...

We report the realization of two-dimensional optical wavelength demultiplexers and multiports for surface plasmons polaritons (SPPs) based on plasmonic crystals, i.e., photonic crystals for SPPs. These SPP elements are built up of lithographically fabricated gold nanostructures on gold thin films. We show by direct imaging of laterally confined SPP beams in the visible spectral range by leakage...

The need to increase transmission capacity in communication networks is becoming very critical. This task can be accomplished by taking advantage of optical networks where techniques such as DWDM and OTDM are combined with the use of all-optical devices to help eliminate electronic bottlenecks. To fulfill these needs a new class of alloptical devices have been proposed and successfully demonstr...
