Figure. Concept of new quantum imaging with ultra-thin nonlinear metasurfaces. The metasurface generates spatially entangled photon pairs, with their emission angle tunable via the pump laser ...

Dispersion is an inherent feature of electromagnetic waves. It allows light to behave differently at different wavelengths, which can be useful, but it also creates chromatic aberrations. As bandwidth ...

FREMONT, Calif.--(BUSINESS WIRE)--Imagia (www.imagia.io), a developer of optical metasurface technology, today announced a breakthrough that allows for optically-accelerated feature detection, ...

Figure 1 Schematic diagram of a nonlinear metasurface composed of asymmetric meta-atoms based on guided mode resonance and bound states in the continuum. Nonlinear optics is a branch of optics that ...

Metasurfaces are two-dimensional (2D), nanoengineered surfaces that interact strongly with electromagnetic waves and can control light with remarkable precision. These ultra-thin layers can be used to ...

A research team has developed a novel multidimensional sampling theory to overcome the limitations of flat optics. The study not only identifies the constraints of conventional sampling theories in ...

Scientists have unveiled a new way to capture ultra-sharp optical images without lenses or painstaking alignment. The approach uses multiple sensors to collect raw light patterns independently, then ...

Imagia, a developer of optical metasurface technology, has announced a “breakthrough” that allows for optically-accelerated feature detection, enabling image processing operations without power ...
