Nanoplasmonic antennas are the one of the major elements in the recognition of upcoming nanoscale wireless communication systems. In this paper, the design and analysis of two multiband antennas operating at optical bands O and L bands, using metal-insulator-metal (MIM) slot waveguide based step impedance resonators (SIRs) and coplanar waveguide (CPW) fed line has been investigated. The simulation results of the two antennas (A) and (B) are obtained by using full wave simulation software (CST Microwave Studio Suite) with the return loss −20 dB and −30.79 dB at desired optical bands. The antenna (A) has a gain of 8 dBi and 7.48 dBi at 1275 nm and 1616 nm wavelengths, similarly antenna (B) has a gain of 8.46 dBi and 6.23 dBi at 1294 nm and 1613 nm wavelengths. The radiation pattern of the simulated results shows the omnidirectional pattern at desired wavelengths, which is very useful for nanoscale wireless communication systems.

“…In view of the development of integrated photonics, various approaches have been proposed to design micro-nano optical components or systems, such as silicon-based waveguides, photonic crystal, plasmonic waveguides, and so on [1][2][3][4]. Among these technologies, it is worthy to point out that the future development of all optical communications and highly integrated photonic circuits may benefit from the research of surface plasmon polaritons (SPPs), which can overcome the classical optical diffraction limits.…”

Plasmonic Bidirectional/Unidirectional Wavelength Splitter Based on Metal-Dielectric-Metal Waveguides

A plasmonic bidirectional/unidirectional wavelength splitter based on asymmetric metal-dielectric-metal (MDM) waveguides is proposed. In the splitter, owing to the interference effects caused by the unequal phase delays from the two asymmetric arms of MDM waveguides, surface plasmon polaritons (SPPs) will only transmit through the output port that is close to the arm where constructive interference arises. The transmission wavelengths can be linearly modulated by changing the lengths of the arms. Since two different SPP modes are obtained in two output ports, respectively, the structure can act as a bidirectional wavelength splitter. Interestingly, both SPP modes can be manipulated to transmit through the same port by adding a notch in one arm. In this case, the notch must simultaneously locate at the anti-node and at the node of the magnetic fields of two SPP modes respectively. As a result, additional phase delay for the specific mode will be produced by the notch, but without any impact on the other mode. Then, the propagation directions of both modes will turn to be identical. High transmission and high cross-talk isolation are investigated for all the cases by using the finite-difference time-domain method.

Rezaei et al [18,19], introduced a distributed circuit model to describe sidecoupled nanoplasmonic structures with MIM arrangement and proposed an efficient circuit model for the analysis and design of rectangular plasmonic resonators. Bahadori et al [20] investigated the optical demultiplexer based on arrayed plasmonic slot cavities by using the transmission line model.…”

We propose a π-network transmission line model to investigate plasmonic metal-dielectric-metal (MDM) waveguides side-coupled with cavity structures. This model can effectively describe the transmission characteristics as a function of coupling distance in our proposed structures. And the π-network transmission line model is promoted to describe transmission spectra and scattering parameters in infinite element structures and periodic structures, which are confirmed by the finite-difference time-domain (FDTD) simulation results. In addition, the slow-light effects in waveguide sidecoupled with periodic cavity structures are researched in our paper. And we first compare the slow-light effects in the plasmonic waveguide side-coupled with cavity structures and stub structures. These observations could be helpful to fundamental research and applications for integrated plasmonic devices.
