Broken time reversal of light interaction with planar chiral nanostructures

Schwanecke, A.S., Krasavin, A.V., Bagnall, D.M., Potts, A., Zayats, A.V. and Zheludev, N.I. (2003) Broken time reversal of light interaction with planar chiral nanostructures Physical Review Letters, 91, (24), 247404-[4pp]. (doi:10.1103/PhysRevLett.91.247404).

Record type: Article


We report unambiguous experimental evidence of broken time-reversal symmetry for the interaction of light with an artificial nonmagnetic material. Polarized color images of planar chiral gold-on-silicon nanostructures consisting of arrays of gammadions show intriguing and unusual symmetry: structures, which are geometrically mirror images, lose their mirror symmetry in polarized light. The symmetry of images can be described only in terms of antisymmetry (black-and-white symmetry) appropriate to a time-odd process. The effect results from a transverse chiral nonlocal electromagnetic response of the structure and has some striking resemblance with the expected features of light scattering on anyon matter.
