Scientists at Stanford University have demonstrated a new way to slow light significantly and to direct it at will. The researchers structured ultrathin silicon chips into nanoscale bars to trap light and then release or redirect it later. These “resonators” could lead to novel ways of manipulating and using light for quantum computing, virtual and augmented reality, and light-based Wi Fi.
