Defect states in three-dimensional diamond photonic band gap crystals
Julia Rocha, Bart A. van Tiggelen, Ad Lagendijk +2
We perform a theoretical study of defect states within the photonic band gap of three-dimensional diamond crystals composed of point scatterers and doped with substitutional defect…
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…
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…
Experimentally mapping the scattering phases and amplitudes of a finite object by optical mutual scattering
Alfredo Rates, Ad Lagendijk, Minh Duy Truong +1
Mutual scattering arises when multiple waves intersect within a finite scattering object, resulting in cross-interference between the incident and scattered waves. By measuring mut…
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…
Symmetries and Wavefunctions of Photons Confined in 3D Photonic Band Gap Superlattices
Marek Kozoň, Ad Lagendijk, Matthias Schlottbom +2
We perform a computational study of confined photonic states that appear in a three-dimensional (3D) superlattice of coupled cavities, resulting from a superstructure of intentiona…
Wavefront shaping through a free-form scattering object
Alfredo Rates, Ad Lagendijk, Aurèle J. L. Adam +2
Wavefront shaping is a technique to study and control light transport inside scattering media. Wavefront shaping is considered to be applicable to any complex material, yet in most…
Analytical modeling of light transport in scattering materials with strong absorption
M. L. Meretska, R. Uppu, G. Vissenberg +3
We have investigated the transport of light through slabs that both scatter and strongly absorb, a situation that occurs in diverse application fields ranging from biomedical optic…
How to distinguish elastically scattered light from Stokes shifted light for solid-state lighting?
M. Meretska, A. Lagendijk, H. Thyrrestrup +3
We have studied the transport of light through phosphor diffuser plates that are used in commercial solid-state lighting modules (Fortimo). These polymer plates contain $\mathrm{YA…
Photonic-Crystal Waveguides with Disorder: Measurement of a Band-Edge Tail in the Density of States

We present time-resolved emission experiments of semiconductor quantum dots in silicon 3D inverse-woodpile photonic band gap crystals. A systematic study is made of crystals with a…
Optimal Concentration of Light in Turbid Materials
E. G. van Putten, A. Lagendijk, A. P. Mosk
In turbid materials it is impossible to concentrate light into a focus with conventional optics. Recently it has been shown that the intensity on a dyed probe inside a turbid mater…
