Trapping Light that Doesn't Bounce off Track for Faster Electronics

News: July 30, 2018
Replacing traditional computer chip components with light-based counterparts will eventually make electronic devices faster due to the wide bandwidth of light. A new protective metamaterial "cladding" prevents light from leaking out of the very curvy pathways it would travel in a computer chip.

Nano-Optical Cables for Wiring Up Photonic Circuits

News: August 21, 2014
Researchers at the University of Alberta, Canada, have proposed a new approach to confining light at subdiffraction wavelengths, using transparent metamaterials—without creating heat or losing data, and with dramatically reduced crosstalk.

Dipole-dipole interactions in nanophotonics

Single photon pulse induced transient entanglement force We show that a single photon pulse incident on two interacting two-level atoms induces a transient entanglement force between them. After absorption of a multi-mode Fock state pulse, the time-dependent atomic interaction mediated by the vacuum...

Vacuum Fluctuations & Casimir forces

Singular evanescent wave resonances in moving media Resonators fold the path of light by reflections leading to a phase balance and thus constructive addition of propagating waves. However, amplitude decrease of these waves due to incomplete reflection or material absorption leads to a finite...
