Wireless communication system via nanoscale plasmonic antennas

Wireless communication system via nanoscale plasmonic antennas

Present on-chip optical communication technology uses near-infrared light, but visible wavelengths would allow system miniaturization and higher energy confinement. Towards this end, we report a nanoscale wireless communication system that operates at visible wavelengths via in-plane information transmission. Here, plasmonic antenna radiation mediates a three-step conversion process (surface pl...

Post-fabrication voltage controlled resonance tuning of nanoscale plasmonic antennas.

Voltage controlled wavelength tuning of the localized surface plasmon resonance of gold nanoparticles on an aluminum film is demonstrated in single particle microscopy and spectroscopy measurements. Anodization of the Al film after nanoparticle deposition forms an aluminum oxide spacer layer between the gold particles and the Al film, modifying the particle-substrate interaction. Darkfield micr...

Adaptive Antennas in Wireless Communication Networks

Wireless Ad-hoc networks can be considered as a means of linking portable user terminals that meet temporarily in locations where connection to a network infrastructure is difficult. Hence, techniques are needed that contribute to the development of high-performance receiving antennas with the capability of automatically eliminating surrounding interference. Solutions to this problem for the co...
