Controlling Plasmonic Field Enhancement via the Interference of Orthogonal Plasmonic Modes Open
Optical nanoantennas concentrate light into their local fields. The field concentration property is governed by the plasmonic resonances and their interference. Here, we present a method for controllable local-field interferences in the ho…

Carrier-envelope phase on-chip scanner and control of laser beams Open
The carrier-envelope phase (CEP) is an important property of few-cycle laser pulses, allowing for light field control of electronic processes during laser-matter interactions. Thus, the measurement and control of CEP is essential for appli…
