Design of a Novel Plasmonic Splitter With Variable Transmissions and Selectable Channels

Plasmonic MIM and MSM Waveguide Couplers for Plasmonic Integrated Computing System

“…Among all the guiding geometries, the MIM WG is a potential platform for highly integrated plasmonic computing system since it supports propagating mode with nanoscale modal size [12] and provides deep-subwavelength field localization with substantial propagation length [13], [14]. As a result, MIM WGs have been employed repeatedly to design devices of a plasmonic computing system like logic gates [15], [16], phase and amplitude modulators [17], [18], power splitters [19], [20], frequency filters [21], [22], interconnect circuits [23], [24], and multiplexers [25].…”

Design of Power Splitters Based on Hybrid Plasmonic Waveguides

“…In photonic integrated circuits, a power splitter is an essential component, which can distribute the energy of incident light to different propagation directions. Various plasmonic power splitters have been proposed, such as 1 × 2 splitters [5][6][7][8], 1 × 3 splitters [9], 1 × N splitters [10][11][12], and variable transmission splitters [13][14][15]. The overwhelming majority of these plasmonic splitters are designed on the basis of metal-insulator-metal (MIM) waveguides, which are composed of two metallic layers and a dielectric layer [5][6][7][8][9][10][11][12][13][14][15].…”

A Tunable and Highly-Efficient Plasmonic Band-Stop Filter at Telecom Wavelengths

“…The MIM structure may be considered as promising for incorporation into PICs, since it maintains an acceptable trade-off between mode confinement and loss. Hence, a number of plasmonic-based structures such as sensors [4], splitters [5], modulators [6], and so forth have been suggested. One of the main and important components in PICs is optical filters that are designed to pass light at a desired frequency range, while blocking other frequencies.…”
