Cutoff-cladding waveguides: Subdiffraction guided modes near cutoff
C. H. Gan
We propose a class of waveguides operating near cutoff such that electromagnetic energy is mainly bound to the cladding rather than the dielectric core to achieve subdiffraction co…
Strong coupling in the far-infrared between graphene plasmons and the surface optical phonons of silicon dioxide
Isaac. J. Luxmoore, Choon How Gan, Peter Q. Liu +4
We study plasmonic resonances in electrostatically gated graphene nanoribbons on silicon dioxide substrates. Absorption spectra are measured in the mid-far infrared and reveal mult…
Broadband and efficient plasmonic control in the near-infrared and visible via strong interference of surface plasmon polaritons
Choon How Gan, Geoffrey R. Nash
Broadband and tunable control of surface plasmon polaritons in the near-infrared and visible spectrum is demonstrated theoretically and numerically with a pair of phased nanoslits.…
Active plasmonic switching at mid-infrared wavelengths with graphene ribbon arrays
Hong-Son Chu, Choon How Gan
An active plasmonic switch based on single- and few-layer doped graphene ribbon array operating in the mid-infrared spectrum is investigated with theoretical and numerical calculat…
Analysis of surface plasmon excitation at terahertz frequencies with highly-doped graphene sheets via attenuated total reflection
Choon How Gan
Excitation of surface plasmons supported by doped graphene sheets at terahertz frequencies is investigated numerically. To alleviate the momentum mismatch between the highly-confin…
Synthesis of highly confined surface plasmon modes with doped graphene sheets in the mid-infrared and terahertz frequencies
Choon How Gan, Hong Son Chu, Er Ping Li
We investigate through analytic calculations the surface plasmon dispersion relation for monolayer graphene sheets and a separated parallel pair of graphene monolayers. An approxim…
Proposal for compact solid-state III-V single-plasmon sources
Choon How Gan, Jean-Paul Hugonin, Philippe Lalanne
We propose a compact single-plasmon source operating at near-infrared wavelengths on an integrated III-V semiconductor platform, with a thin ridge waveguide serving as the plasmon…
