The identification of a complete three-dimensional (3D) photonic band gap in real crystals typically employs theoretical or numerical models that invoke idealized crystal structures. Such an approach is prone to false positives (gap wrongly assigned) or false negatives (gap missed). Therefore, we propose a purely experimental probe of the 3D photonic band gap that pertains to any class of photonic crystals. We collect reflectivity spectra with a large aperture on exemplary 3D inverse woodpile…

X-ray Imaging of Functional Three-Dimensional Nanostructures on Massive Substrates

TLDR
TXT identifies why nanostructures that look similar in electron microscopy have vastly different nanophotonic functionality: one “good” crystal with a broad photonic gap reveals 3D periodicity as designed; a second “bad” structure without a gap reveals a buried void, and a third “ugly” one without gap is shallow due to fabrication errors.

Enhanced Absorption in thin and ultrathin silicon films by 3D photonic band gap back reflectors

Since thin silicon film solar cells have limited optical absorption, we explore the 14 effect of a nanostructured back reflector to recycle the unabsorbed light. As a back reflector, we 15

TLDR
Single crystals of silicon inverse opal with a complete three-dimensional photonic bandgap centred on 1.46 µm are described, produced by growing silicon inside the voids of an opal template of close-packed silica spheres that are connected by small ‘necks’ formed during sintering, followed by removal of the silica template.
