Atom-thin 2D laser promises advanced photonics for quantum computing

A team from the US Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) has created a 2D laser just one molecule thick that promises to make significant advances in ultra-compact photonic components for the likes of quantum computers and the next generation of optoelectronic devices.

"Our observation of high-quality excitonic lasing from a single molecular layer of tungsten disulfide marks a major step towards two-dimensional on-chip optoelectronics for high-performance optical communication and computing applications," said Xiang Zhang, director of Berkeley Lab's Materials Sciences Division and the leader of this study.

Working on previous research where the Berkeley Lab team created a "whispering gallery microcavity" for plasmons (a "whispering gallery" is usually a circular or hemispherical structure where whispered acoustic communication is possible from any part of the internal circumference to any other; this same effect can be replicated in an analogous way with light), they developed a modified version for excitions.
