Photonic crystals: Disorder sets light straight

Photonic crystals can control the flow of light but they are extremely sensitive to structural disorder. Although this often degrades performance, disorder can actually be used to enhance light collimation. As they report in NaturePhysics, Pin-ChunHsieh and colleagues demonstrate how disorder can en...

Zusammenfassung:Photonic crystals can control the flow of light but they are extremely sensitive to structural disorder. Although this often degrades performance, disorder can actually be used to enhance light collimation. As they report in NaturePhysics, Pin-ChunHsieh and colleagues demonstrate how disorder can enhance the collimation of light through Anderson localization awave phenomenon that only emerges in disordered systems.
