Optically dense nanowire metamaterials are transparent to polarization
Shravan Raghunathan, Ad Lagendijk, Willem L. Vos
We study the transport of light through dense opaque anisotropic metamaterials consisting of oriented nanowires. The nanowires consist of polymer photoresist that is structured by…
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…
Mesoscopic Theory of Wavefront Shaping to Focus Waves inside Disordered Media
B. A. van Tiggelen, A. Lagendijk, Willem L. Vos
We describe the {theory of focusing waves} to a predefined spatial point {inside} a disordered {three-dimensional medium} by the external shaping of {} different field sources o…
Probing the position-dependent optical energy fluence rate in three-dimensional scattering samples
Ozan Akdemir, Minh Duy Truong, Alfredo Rates +2
The accurate determination of the position-dependent energy fluence rate of scattered light (which is proportional to the energy density) is crucial to the understanding of transpo…
