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…
Resolving features and derivatives in noisy data using weighted Whittaker-Henderson smoothing
Bert Mulder, Ad Lagendijk, Willem L. Vos
A frequently occurring challenge in experimental and numerical observations is how to resolve features, such as spectral peaks - with center, width, height - and derivatives from m…
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…
