Integrated Metal-Insulator-Metal Plasmonic Nano Resonator: An Analytical Approach

“…FDTD simulations are used to confirm the accuracy of this model. This FDTD has been recently proved to show good match with the experimental measurements [5,6]. Thus, the good match between our model and the FDTD suggests a good match with the experimental results.…”

“…Due to its ultra small core size, the coupling to and from this core is challenging. Recently, this coupling dilemma has been resolved by introducing a novel non-resonant coupling mechanism to and from the conventional silicon waveguide and the plasmonics slot waveguide (PSW); a 3D version of this MIM configuration has been proposed [5,6]. On the other hand, in order to avoid the propagation loss impact on the performance of the plasmonic devices, the device length has to be in the order of a few microns only.…”

Nanoscale highly selective plasmonic quad wavelength demultiplexer based on a metal–insulator–metal

“…However, coupling to a MIM waveguide with a few nanometerwide cores is very challenging. Albeit the difficulties, coupling to an MIM waveguide can be achieved throughout the use of hybrid junctions [4,5]. This technique provides an efficient, wideband, and non-resonant coupling scheme to and from a silicon rib waveguide.…”

“…These devices include band-pass and band-reject filters [6], resonators [7,8], interferometers [4,7,9], couplers [4,10], demultiplexers [6], logic gates [11], power splitters [12], and on chip sensors [13], which led the way for nanoscale optical system using plasmonic circuitry [1]. For such optical system with complex functionality, multiple channel operation is necessary.…”

Tunable Nanoplasmonics

“…Moreover, good coupling efficiency to this waveguide with few nanometers gap is the bottleneck of using such waveguides. Recently, a novel coupling mechanism is proposed, fabricated and tested with more than 70% coupling efficiency [1], [2].…”
