Invisibility has long been one of the marvels in science fiction and fantasy – and more recently in physics.

A new optical device made of silicon “nanopillars” could lead to advanced microscopes, displays, sensors, and cameras that can be mass-produced using the same techniques used to manufacture computer microchips.

Researchers have discovered a new way to make ultrasensitive conductivity measurements at optical frequencies on high-speed nanoscale electronic components.

Most lenses rely on a curved shape to bend and focus light. But these lenses take up too much space in consumer electronics and fiber-optic systems.

Researchers are developing vision-correcting displays for computer monitors that would let people see text and images clearly without their glasses or contact lenses.
