Dispersion of backward-propagating waves in a surface defect on a 3D photonic band gap crystal

Timon J. Vreman, Melissa J. Goodwin, Lars J. Corbijn van Willenswaard +3

We experimentally study the dispersion relation of waves in a two-dimensional (2D) defect layer with periodic nanopores that sits on a three-dimensional (3D) photonic band gap crys…
