Non-linear bistability in pulsed optical traps
Alex J. Vernon, Francisco J. Rodríguez-Fortuño, Anatoly V. Zayats
Optical trapping, also known as optical tweezing or optical levitation, is a technique that uses highly focused laser beams to manipulate micro- and nanoscopic particles. In optica…

Polarisation Control of Nanoantenna Cold Spots
Alexander J. Vernon, Francisco J. Rodríguez-Fortuño
Cold spots are sub-wavelength regions which might emerge near a plasmonic nanoantenna, should one or more components of some far-field illumination cancel out with scattered light.…
