Until now, optical antennas could almost always be described classically: the electrons of the metal simply stop at the edge ...

optical antennas, surface plasmon and phonon polaritons, extreme nonlinear optics, strong light matter interaction. Scanning probe near-field optical microscopy and spectroscopy, optical forces, and ...

With thousands or even millions of tiny antennas in an array, each only 1 micrometer wide, the researchers can capture the scattered light with an optical microscope and measure electrical signals ...

Instead of relying on traditional wires, the team designed tiny antennas that convert electrical signals into light, which can be measured using standard optical microscopes commonly found in ...
