Description
Jun Peng and a large team of co-authors build a photonic crystal whose light-blocking band can be switched on and off. Their 2024 paper uses vanadium dioxide, a material that flips from insulator to metal near room temperature and changes its optical behavior sharply in the process. Fixed crystals have a fixed band gap; adaptive devices need one that moves on command.
The team formed the crystal as an inverse opal, coating a sacrificial template with the material by atomic layer deposition, then annealing it with tight control. The finished structure steers its band gap across the near-infrared range as the material switches state. Such tunable crystals could serve filters, sensors, and light-routing parts in future optical hardware.
