Spatially shaping waves to penetrate deep inside a forbidden gap
Ravitej Uppu, Manashee Adhikary, Cornelis A. M. Harteveld +1
It is well known that waves incident upon a crystal are transported only over a limited distance - the Bragg length - before being reflected by Bragg interference. Here, we demonst…
Reflectivity of Finite 3D GaAs Photonic Band Gap Crystals
Takeyoshi Tajiri, Shun Takahashi, Cornelis A. M. Harteveld +3
We study the optical reflectivity of three-dimensional (3D) photonic band gap crystals with increasing thickness. The crystals consist of GaAs plates with nanorod arrays that are a…
Experimental probe of a complete 3D photonic band gap
Manashee Adhikary, Ravitej Uppu, Cornelis A. M. Harteveld +2
The identification of a complete three-dimensional (3D) photonic band gap in real crystals always employs theoretical or numerical models that invoke idealized crystal structures.…
X-ray imaging non-destructively identifies functional 3D photonic nanostructures
D. A. Grishina, C. A. M. Harteveld, A. Pacureanu +4
To investigate the performance of three-dimensional (3D) nanostructures, it is vital to study in situ their internal structure non-destructively. Hence, we perform synchrotron X-ra…
Looking inside three-dimensional (3D) silicon photonic band gap crystals
W. L. Vos, D. A. Grishina, P. Cloetens +2
We have performed an x-ray holotomography study of a three-dimensional (3D) photonic band gap crystal. The crystals was made from silicon by CMOS-compatible methods. We manage to o…
Method to make a single-step etch mask for 3D monolithic nanostructures
D. A. Grishina, C. A. M. Harteveld, L. A. Woldering +1
Current nanostructure fabrication by etching is usually limited to planar structures as they are defined by a planar mask. The realisation of three-dimensional (3D) nanostructures…
