Focusing of light beyond the diffraction limit

K. R. Chen

Diffraction limits the behaviour of light in optical systems and sets the smallest achievable line width at half the wavelength. With a novel subwavelength plasmonic lens to reduce…

Beyond-limit light focusing in the intermediate zone

K. R. Chen, W. H. Chu, H. C. Fang +10

We experimentally demonstrate that a new nanolens of designed plasmonic subwavelength aperture can focus light to a single-line with its width beyond the diffraction limit that set…
