The resulting light field displays a high level of axial confinement, with experimental demonstrations given through two-photon microscopy and the non-linear ... focal spot is expected to contain ...

Plasmonic nanoantennas provide unprecedented opportunities to concentrate light fields in subwavelength ... we compared the linear and nonlinear spectra of an array of bare gold nanoantennas ...

Optical physicists in the UK and Spain have fabricated an array of nanoholes that can focus light into a spot that is smaller than the wavelength of light used. The research team, led by Nikolay ...

Scientists using radio wavelength data from the Australian Square Kilometre Array Pathfinder (ASKAP) spotted a strangely symmetrical sphere located thousands of light-years away. The “sphere ...
