Highly non-linear metamaterials for laser technology - a million times better

Nonlinear optical materials are widely used in laser systems. However, high light intensity and long propagation are required to produce strong nonlinear optical effects. Researchers created metamaterials with a million times stronger nonlinear optical response, compared to the traditional nonlinear materials, and demonstrated frequency conversion in films 100 times thinner than human hair using light intensity comparable to that of a laser pointer.

Overcoming light scattering: New optical system sees deeper inside tissue

Optical imaging could become even more valuable if researchers could find a way for light to penetrate all the way through the body's tissues. Currently, passing through a fraction of an inch of skin is enough to scatter the light and scramble the image. Now researchers have developed a single-pixel optical system based on compressive sensing that can overcome the fundamental limitations imposed by this scattering.

Superconducting-silicon qubits

Theorists propose a way to make superconducting quantum devices such as Josephson junctions and qubits, atom-by-atom, inside a silicon crystal. Such systems could combine the most promising aspects of silicon spin qubits with the flexibility of superconducting circuits.
