Making light ‘feel’ a magnetic field like an electron would

Researchers have now experimentally made light effectively “feel” a magnetic field within a complicated structure called a photonic crystal. Within the crystal, the light spins in circles and the researchers observed, for the first time, that it forms discrete energy bands, called Landau levels, paralleling a well-known phenomenon seen in electrons.

Light stands still in a deformed crystal

AMOLF researchers, in collaboration with Delft University of Technology, have succeeded in bringing light waves to a halt by deforming the two-dimensional photonic crystal that contains them. The researchers show that even a subtle deformation can have a substantial effect on photons in the crystal. This resembles the effect that a magnetic field has on electrons.

Observation of Landau levels and chiral edge states in photonic crystals through pseudomagnetic fields induced by synthetic strain

Control over light propagation and localization in photonic crystals offers wide applications ranging from sensing and on-chip routing to lasing and quantum light–matter interfaces. Although in electronic crystals, magnetic fields can be used to induce a multitude of unique phenomena, the uncharged nature of photons necessitates alternative approaches to bring about similar control over photons at the nanoscale. Here we experimentally realize pse
