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…
The local density of optical states in the 3D band gap of a finite photonic crystal
Charalampos P. Mavidis, Anna C. Tasolamprou, Shakeeb B. Hasan +5
A three-dimensional (3D) photonic band gap crystal is an ideal tool to completely inhibit the local density of optical states (LDOS) at every position in the crystal throughout the…
Deterministic and controllable photonic scattering media via direct laser writing
E. Marakis, R. Uppu, M. L. Meretska +3
Photonic scattering materials, such as biological tissue and white paper, are made of randomly positioned nanoscale inhomogeneities in refractive index that lead to multiple scatte…
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…
