Nano-Plasmonic Filters Based on Tooth-Shaped Waveguide Structures
Along with development of human society and technology, it becomes more dependable on the miniaturization and integration of semiconductor components, circuits and devices. The performance of integrated circuits, such as micro-processor, is in accordance with the famous Moore’s law that the number of transistors placed inexpensively on an integrated circuit doubles approximately every two years...

متن کاملGuiding properties of asymmetric hybrid plasmonic waveguides on dielectric substrates
We proposed an asymmetric hybrid plasmonic waveguide which is placed on a substrate for practical applications by introducing an asymmetry into a symmetric hybrid plasmonic waveguide. The guiding properties of the asymmetric hybrid plasmonic waveguide are investigated using finite element method. The results show that, with proper waveguide sizes, the proposed waveguide can eliminate the influe...
متن کاملSilicon-based plasmonic waveguides.
We propose and comprehensively investigate Si-based plasmonic waveguides as a means to confine and manipulate photonic signals. The high refractive index of Si assures strong confinement and a very high level of photonic integration with achievable waveguide separations of the order of 10 nm and waveguide bends with 500 nm radius at telecommunication wavelengths, while using Al and Cu plasmonic...
متن کاملStudies on Plasmonic Waveguides and Devices
Over, the past decade researchers have come up with a new technology, named "Plasmonics" which has the potential of realizing miniaturized nanophotonic circuits, having the compactness of electronic circuit and the bandwidth of photonic networks. In plasmonic waveguides, the optical guidance is mediated by the electromagnetic wave propagating along a metal/dielectric interface, which arises due...
