High-efficiency light-wave control with all-dielectric optical Huygens' metasurfaces
Optical metasurfaces have developed as a breakthrough concept for advanced wave-front engineering enabled by subwavelength resonant nanostructures. However, reflection and/or absorption losses as well as low polarisation-conversion efficiencies pose a ...

Frequency converter implementing an optical analogue of the cosmological redshift
According to general relativity, the frequency of electromagnetic radiation is altered by the expansion of the universe. This effect--commonly referred to as the cosmological redshift--is of utmost importance for observations in cosmology.

High Power, High Efficiency, Continuous-Wave Supercontinuum Generation using Standard Telecom Fibers
We demonstrate a simple module for octave spanning continuous-wave supercontinuum generation using standard telecom fiber. This module can accept any high power Ytterbium-doped fiber laser as input.

Cavity cooling of a levitated nanosphere by coherent scattering
We report three-dimensional cooling of a levitated nanoparticle inside an optical cavity. The cooling mechanism is provided by cavity-enhanced coherent scattering off an optical tweezer.

Goos-Haenchen and Imbert-Fedorov shifts of a nondiffracting Bessel beam
Goos-Haenchen and Imbert-Fedorov shifts are diffractive corrections to geometrical optics that have been extensively studied for a Gaussian beam that is reflected or transmitted by a dielectric interface.

Geometric limits to geometric optical imaging with infinite, planar, non-absorbing sheets
New ray-optical elements allow generalized refraction of light rays, but geometry imposes limitations on possible mappings between the positions of an object and its geometric image.

Nonlocality in uniaxially polarizable media
We reveal extraordinary electromagnetic properties for a general class of uniaxially polarizable media. Depending on parameters, such metamaterials may have wide range of nontrivial shapes of isofrequency contours including lemniscate, diamond and ...
