Over the last two decades, the capabilities of metasurfaces in light modulation with
subwavelength thickness have been proven, and metasurfaces are expected to miniaturize …

Optical superoscillations are rapid, subwavelength spatial variations of the intensity and
phase of light, occurring in complex electromagnetic fields formed by the interference of …

Dispersion engineering is essential to the performance of most modern optical systems
including fiber-optic devices. Even though the chromatic dispersion of a meter-scale single …

Artificially engineered metasurfaces provide extraordinary wave control at the
subwavelength scale. However, metasurfaces proposed so far suffer due to limited …

The refractive-lens technique has been well developed over a long period of evolution,
offering powerful imaging functionalities, such as microscopes, telescopes, and …

An inverse-designed metalens is proposed, designed, and fabricated on an optical fiber tip
via a 3D direct laser-writing technique through two-photon polymerization. A computational …

The Wigner function was formulated in 1932 by Eugene Paul Wigner, at a time when
quantum mechanics was in its infancy. In doing so, he brought phase space representations …

Existing methods of correcting for chromatic aberrations in optical systems are limited to two
approaches: varying the material dispersion in refractive lenses or incorporating grating …

Superoscillations are band-limited functions with the counterintuitive property that they can
vary arbitrarily faster than their fastest Fourier component, over arbitrarily long intervals …

Label‐free super‐resolution (LFSR) imaging relies on light‐scattering processes in
nanoscale objects without a need for fluorescent (FL) staining required in super‐resolved FL …
