Journal ArticleDOI
Preparation of photonic crystals made of air spheres in titania
TL;DR: Three-dimensional crystals of air spheres in titania with radii between 120 and 1000 nanometers were made by filling the voids in artificial opals by precipitation from a liquid-phase chemical reaction and subsequently removing the original opal material by calcination and are a new class of photonic band gap crystals for the optical spectrum.
Journal ArticleDOI
Controlling the dynamics of spontaneous emission from quantum dots by photonic crystals
Peter Lodahl,A. Floris van Driel,Ivan S. Nikolaev,Arie Irman,Karin Overgaag,Daniel Vanmaekelbergh,Willem L. Vos +6 more
TL;DR: In this paper, the spectral distribution and time-dependent decay of light emitted from excitons confined in the quantum dots are controlled by the host photonic crystal, and both inhibited and enhanced decay rates are observed depending on the optical emission frequency.

Controlling the dynamics of spontaneous emission from quantum dots by photonic crystals
Peter Lodahl,A. Floris van Driel,Ivan S. Nikolaev,Arie Irman,Karin Overgaag,Daniel Vanmaekelbergh,Willem L. Vos +6 more
TL;DR: This work shows that the spectral distribution and time-dependent decay of light emitted from excitons confined in the quantum dots are controlled by the host photonic crystal, providing a basis for all-solid-state dynamic control of optical quantum systems.
Journal ArticleDOI
Non-invasive imaging through opaque scattering layers
Jacopo Bertolotti,Jacopo Bertolotti,Elbert G. van Putten,Elbert G. van Putten,Christian Blum,Ad Lagendijk,Ad Lagendijk,Willem L. Vos,Allard Mosk +8 more
TL;DR: An optical method is reported that allows non-invasive imaging of a fluorescent object that is completely hidden behind an opaque scattering layer and can be generalized to other contrast mechanisms and geometries.
Journal ArticleDOI
Scattering lens resolves sub-100 nm structures with visible light.
E.G. van Putten,Duygu Akbulut,Jacopo Bertolotti,Jacopo Bertolotti,Willem L. Vos,Aart Lagendijk,Aart Lagendijk,Allard Mosk +7 more
TL;DR: This work introduces a new type of lens that exploits multiple scattering of light to generate a scanning nanosized optical focus and is the first lens that provides a resolution better than 100 nm at visible wavelengths.
