Polarization-Controlled Chromo-Encryption

Olivier Martin, Hsiang-Chu Wang

The response of simple plasmonic nanorods to polarized illumination is studied in detail. Depending on the orientation of that polarization with respect to the symmetry axes of the nanostructure, a chiral response can occur, which can be analyzed through a ...

Second-harmonic generation in atomically thin 1T-TiSe2 and its possible origin from charge density wave transitions

László Forró, Helmuth Berger

Optical second-harmonic generation (SHG) can only occur in noncentrosymmetric crystals in the leading electric-dipole approximation. Transition metal dichalcogenides with the 1T octahedral coordination is centrosymmetric, hence precluding SHG. Here we repo ...
