[Excerpt]

A group of researchers, led by researchers from the University of Illinois, have managed to develop the first optoelectronically active 3D photonic crystal. The development could enable new advancements for solar cells, lasers, metamaterials and more.

…

To test their technique, the group built a 3D photonic crystal LED the first such working device. The LED demonstrates that the concept produces functional devices, but by tweaking the structure or using other semiconductor materials, the researchers believe they can improve solar collection or target specific wavelengths for metamaterials applications or low-threshold lasers.
