Inverse designed extended depth of focus meta-optics for broadband imaging in the visible [PDF]

Nanophotonics, 2021
We report an inverse-designed, high numerical aperture (∼0.44), extended depth of focus (EDOF) meta-optic, which exhibits a lens-like point spread function (PSF).

Metasurface Optics for Full-color Computational Imaging [PDF]

Science Advances, 2018
Conventional imaging systems comprise large and expensive optical components which successively mitigate aberrations. Metasurface optics offers a route to miniaturize imaging systems by replacing bulky components with flat and compact implementations ...

Perfect lenses in focus [PDF]

Nature, 2011
Materials that refract light backwards are thought to be required for making super-resolution lenses. An alternative proposal — that conventional, positively refracting media can do the job — has met with controversy. Two experts from either side of the debate lay out their views on the matter.

Polarisation optics for biomedical and clinical applications: a review [PDF]

Light: Science & Applications, 2021
Many polarisation techniques have been harnessed for decades in biological and clinical research, each based upon measurement of the vectorial properties of light or the vectorial transformations imposed on light by objects.

Bifunctional catalytic effect of Mo2C/oxide interface on multi-layer graphene growth

Scientific Reports, 2021
The role of the Mo2C/oxide interface on multi-layer graphene (MLG) nucleation during a chemical vapor deposition (CVD) process is investigated. During the CVD process, MLG growth is only observed in the presence of a Mo2C/SiO2 interface, indicating that ...

Enhanced Depth of Focus Intraocular Lenses: Through Focus Evaluation of Wavefront-Shaping versus Diffractive Optics

Biomedicine Hub, 2023
Introduction: A new class of nondiffractive, wavefront-shaping Enhanced-Depth-of-Focus (EDoF) IOLs has been introduced very recently to cope with photic phenomena known from diffractive EDoF IOLs.

Focus on modern frontiers of matter wave optics and interferometry [PDF]

, 2012
The level of experimental control and the detailed theoretical understanding of matter wave physics have led to a renaissance of experiments testing the very foundations of quantum mechanics and general relativity, as well as to applications in metrology.
