Double Helical Plasmonic Antennas

open access: yesAdvanced Functional Materials, EarlyView.
Plasmonic double helical antennas funnel circularly polarized light to the nanoscale, offering strong chiroptical interaction and directional light emission. Extending a single helix design tool, this study combines numerical modeling with experimental validation, revealing large, broadband dissymmetry factors in the visible range.

Quantum telecommunication based on atomic cascade transitions [PDF]

open access: yesPhysical Review Letters 96, 093604 (2006), 2006
A quantum repeater at telecommunications wavelengths with long-lived atomic memory is proposed, and its critical elements are experimentally demonstrated using a cold atomic ensemble. Via atomic cascade emission, an entangled pair of 1530 nm and 780 nm photons is generated.

European Telecommunication Regulation - Effects on Telecommunication Providers [PDF]

open access: yesSSRN Electronic Journal, 2010
This paper considers the impact of European telecom regulation on the value of affected companies. Employing a repeating AR-GARCH model, I compare the effect of three types of regulation which are categorized based on the addressed subject, i.e. cross-market, country-specific and company-specific regulation.
