Improved Plasmonic Demultiplexer Based on Tapered and Rectangular Slot MIM Waveguide
نویسنده
چکیده
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 used to develop ultra-compact photonic wavelength demultiplexing devices for large-scale photonic integration. Keywords—Photonic integrated devices, Plasmonics, Metalinsulator-metal (MIM) waveguide, Demultiplexers.

متن کاملLoss measurement of plasmonic modes in planar metal-insulator-metal waveguides by an attenuated total reflection method.
We report experimental excitation and characterization of surface plasmon modes in planar metal-insulator-metal (MIM) waveguides. Our approach is based on determining the width of the reflection angular spectrum in the attenuated total reflection (ATR) configuration. Owing to its transverse character, the ATR configuration provides a more straightforward and simpler way to determine the loss of...

A compact wavelength demultiplexing structure based on arrayed metal-insulator-metal (MIM) slot cavities is proposed and demonstrated numerically. The structure consists of a bus waveguide perpendicularly coupled with a series of slot cavities, each of which captures SPPs at the resonance frequency from the bus waveguide and tunes the transmission wavelength by changing its geometrical paramete...
متن کاملCharacterization of the loss of plasmonic modes in planar metal-insulator-metal waveguides by a coupling-simulation approach.
Metal-insulator-metal (MIM) structures have been the subject of great interest as nanoscale plasmonic waveguides. The modeling and measurement of the loss in these waveguides is one of the critical issues in realizing the plasmon-based nanocircuitry. Due to the subwavelength size of the structure, the light injection and the measurement of the loss in MIM structures typically require tapered fi...
متن کاملTransmittance of MIM Waveguides Containing Semi-Circular Ring Shaped and Rectangular Ring Shaped Grooves
In this paper the transmittance of metal-insulator-metal (MIM) waveguides containing semi-circular ring shaped and rectangular ring shaped grooves are investigated. By varying groove parameters their effects on the transmittance of the MIM waveguides are investigated. The results show that the transmittance spectra of the waveguides have maximum and minimum points, and by using appropriate para...
