MEMS plasmonic switch with stripe plasmonic waveguide
2017 22nd Microoptics Conference (MOC), 2017We designed the new plasmonic switch that combines a stripe plasmonic waveguide and MEMS. On-off extinction ratio and mechanical modulation resonance frequency was numerically estimated to be 10 dB and 70 kHz, respectively. We confirmed the displacement of moving part depending on applied voltage.

Characteristics of plasmonic waveguides for coupled wedge plasmons
SPIE Proceedings, 2006We have numerically investigated characteristics of plasmonic waveguides for coupled wedge plasmons (CWPs) consisting two silver wedges separated by a nano gap all on a glass substrate. Three types of waveguides for CWPs on a glass substrate are considered: (1) two metallic wedges on a planar substrate, (2) two metallic wedges built into the ...

MEMS plasmonic switch with stripe plasmonic waveguide
Japanese Journal of Applied Physics, 2018Abstract In this study, we fabricated a plasmonic waveguide switch combining MEMS with a stripe plasmonic waveguide for optical signal processing using electron-beam lithography. The outgoing waveguide was moved by the electrostatic attractive force of the comb-teeth portion, and the ON/OFF states of the output light were switched by ...

Kerr effect in hybrid plasmonic waveguides
Journal of the Optical Society of America B, 2016Hybrid plasmonic waveguides, in which light is guided by a combination of dielectric and plasmonic confinement, are likely to play a key role in compact nonlinear optical devices. Although their absorption loss is considerable, through a small device footprint and careful optimization, a significant nonlinear phase shift may be achieved. Here, we study

Single Nanoparticle Couplers for Plasmonic Waveguides
Small, 2014A single nanoparticle antenna, can be used as an efficient coupler for plasmonic nanowire waveguides. The coup-ling of light into the surface plasmon polaritons on a nanowire can be suppressed or enhanced depending on the surface plasmon resonances of the nanoantenna. The coupler is compacted and can be simply controlled using focus ion beam.

Introduction to Surface Plasmon-Polariton Waveguides
2010This chapter summarizes basic properties of the main Surface plasmon polariton (SPP) modes. SPPs are electromagnetic (EM) excitations that, being coupled to surface collective oscillations of free electrons in a metal, are bound to and propagate along metal-dielectric interfaces.
