Momentum-resolved reflectivity of a 2D photonic crystal in the near-infrared
Timon J. Vreman, Melissa J. Goodwin, Ad Lagendijk +1
Two-dimensional (2D) photonic crystals offer strong control over the propagation of light through their bands. Theoretical methods for computing the band structure in 2D are well-e…

Radiative local density of states in three-dimensional photonic band-gap crystals to interpret time-resolved emission
Timon J. Vreman, Ad Lagendijk, Willem L. Vos
We investigate the spontaneous emission of light in three-dimensional (3D) photonic crystals through theoretical calculations and simulations. It is well known that spontaneous emi…

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…
