Description
Highly localized plasmonic vortices carrying orbital angular momentum are of importance for many applications. Yet, it is a challenge to generating plasmonic vortex with a high topological charge because of no available technique. Here, a novel pl...

Description
Through a computational model, we study the coherence converting capabilities of an array of holes in a surface plasmon-supporting metal plate, with an eye towards the creation of controlled coherence plasmonic light sources. We evaluate how the a...

Description
We present an analysis of the propagation properties of a recently introduced class of conjugate mode partially coherent beams (called double-H beams) in a turbulent atmosphere using the extended Huygens-Fresnel integral. We investigate how the ph...
