Nanoantennae Show Promise for Subwavelength Optical Microscopy
Researchers have fabricated optical nanoantennae on the end face of a near-field probe. Using single fluorescent molecules, they measured the antennae’s resonance, excitation conditions and field localization, showing that the constructs are similar to the radio-frequency monopole antenna.
The scientists, from Institut de Ciencies Fotoniques in Barcelona, Spain, and from the University of Twente in Enschede and the Institute for Atomic and Molecular Physics in Amsterdam, both in the...
