Low-Energy Nanolaser Shines in all Directions

Imperfections and irregularities are unavoidable in nanoscience due to the limited level of control of nanofabrication processes. Disorder is potentially detrimental to nanosystems but if well-contained, disorder could lead to novel physical concepts and applications. By introducing a slight degree of disorder in nanolasers, the laser no longer emits in one specific direction but in all directions.
