Unconventional Flatband Line States in Photonic Lieb Lattices
Shiqi Xia, Ajith Ramachandran, Shiqiang Xia +9
Flatband systems typically host "compact localized states"(CLS) due to destructive interference and macroscopic degeneracy of Bloch wave functions associated with a dispersionless…

Flat-band localization and self-collimation of light in photonic crystals
Nojoon Myoung, Hee Chul Park, Ajith Ramachandran +2
We investigate the optical properties of a photonic crystal composed of a quasi-one-dimensional flat-band lattice array through finite-difference time-domain simulations. The photo…
