Researchers found a way to develop bright, efficient and color­ful OLEDs.

New method allows the simultaneous fabrication of multiple structural colors responsive to mechanical stimuli.

A solid-state laser with narrow linewidth is obtained with two stages of sum frequency generation in LBO crystals.

The new device can be simultaneously used as a touch screen, ambient light sensor and image sensor.

A new method to simulate and explore interactions between artificial atoms.

New material shows a large nonreciprocal absorption of light depending on the direction of light propagation.

The metamaterial is formed by randomly oriented bi-material nanocylinders in a host medium.

Amorphous solids selectively absorb light of different polarizations.
