‘Bow ties’ break record for bottling up light

Tiny silicon bowtie structure claims record photon confinement in time and space.

A newly designed photonic crystal traps light using a series of bow-tie-shaped gaps. Photon density (depicted in 3D for easy visualization) is highest at the centre of the bow tie’s knot (red) and dwindles (from yellow to green to purple) towards the knot’s outer edges. Credit: Ella Maru Studio
