Non-utopian optical properties computed of a tomographically reconstructed real photonic nanostructure
Lars J. Corbijn van Willenswaard, Stef Smeets, Nicolas Renaud +3
State-of-the-art computational methods combined with common idealized structural models provide an incomplete understanding of experiments on real nanostructures, since manufacturi…
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…
Unsupervised Machine Learning to Classify the Confinement of Waves in Periodic Superstructures
Marek Kozoň, Rutger Schrijver, Matthias Schlottbom +2
We employ unsupervised machine learning to enhance the accuracy of our recently presented scaling method for wave confinement analysis [1]. We employ the standard k-means++ algorit…
Enhanced Absorption in thin and ultrathin silicon films by 3D photonic band gap back reflectors
Devashish Sharma, Shakeeb B. Hasan, Rebecca Saive +2
Since thin-film silicon solar cells have limited optical absorption, we explore the effect of a nanostructured back reflector to recycle the unabsorbed light. As a back reflector w…
Reflectivity calculated for a 3D silicon photonic band gap crystal with finite support
D. Devashish, Shakeeb B. Hasan, J. J. W. van der Vegt +1
We study numerically the reflectivity of three-dimensional (3D) photonic crystals with a complete 3D photonic band gap, with the aim to interpret recent experiments. We employ the…
