Light that twists as it travels and materials whose internal order is knotted like a pretzel are starting to collide in the ...

Asymmetric optical transmission refers to the engineered phenomenon whereby light propagates with different efficiencies in opposite directions within a photonic structure. This effect is achieved by ...

Degenerate band edge (DBE) phenomena represent a striking feature in periodic photonic structures, in which four Bloch eigenmodes coalesce at a unique point in the dispersion diagram. This degeneracy ...

Over the past decades, engineers have introduced numerous technologies that rely on light and its underlying characteristics. These include photonic and quantum systems that could advance imaging, ...

Many of today’s computing and communications applications demand almost unimaginable processing capability and high-bandwidth access to memory. For example, many data center systems using high-end ...

(Nanowerk Spotlight) The vibrant blue of a morpho butterfly's wings doesn't come from pigments but from light interacting with microscopic structures on its surface. This phenomenon – structural color ...

Controlled generation of single-photon emitters in silicon (red) by broad-beam implantation of ions (blue) through a lithographically defined mask (left) and by a scanned focused ion beam (right).

Slight temperature changes, imperceptible manufacturing imperfections, and heat generated by their own components can completely ruin an entire quantum quantum system-on-chip. Silicon photonics could ...

Science X is a network of high quality websites with most complete and comprehensive daily coverage of the full sweep of ...

Fig. 1 Schematic and theoretical results of strong-confinement rib-loaded waveguide. (a) Schematic of strong-confinement rib-loaded waveguide with electrodes. The inset shows the cross-section view of ...

Optical neural networks may provide the high-speed and large-capacity solution necessary to tackle challenging computing tasks. However, tapping their full potential will require further advances. One ...
