Abstract/OtherAbstract:
The spatial structure of light with Orbital Angular Momentum, or "twisted light", closely resembles the shape of atomic wavefunctions. It could therefore make symmetry-forbidden transitions in quantum dots possible. However, the vanishing intensity in the center of an OAM beam usually makes this effect weak. Here we show a plasmonic approach to focus OAM light to sub-wavelength dimensions using metallic nanoscale resonant optical antennas, allowing to increase the interaction strength by 3 orders of magnitude.
