Significance of output:

Inverting the conventional light-localizing mode of photonic nanoantenna operation, this ground-breaking study demonstrates that such structures can resonantly couple energy from a nanoscale excitation to far-field light. It relies on and vividly illustrates the power of spatially resolved electron-induced emission spectroscopy techniques pioneered in Southampton, which link light output to fundamental geometric and material properties, increasingly adopted and followed in the international nanophotonics community (e.g. at AMOLF doi:10.1557/mrs.2012.174, Berkeley doi:10.1103/PhysRevLett.106.037402, Milan/Taiwan/Wurzburg doi:10.1088/0034-4885/75/2/024402). In underpinning core themes of an EPSRC programme grant at Southampton (EP/G060363/1, £5M, 01/2010-12/2015) it is facilitating further breakthroughs in nanoscale coherent light emission (doi:10.1103/PhysRevLett.109.217401).
