Diffraction imaging of cracks in self-assembled photonic crystals

S Rao, R Shaw, D Rout, G Kumar, R Vijaya, S Gupta - Optical Materials, 2019 - Elsevier
We demonstrate a non-invasive technique, based on diffraction imaging, to remotely detect
and characterize cracks in self-assembled photonic crystals. Through this technique, we …

Colloidal self-assembly of highly-ordered silica inverse opals for deep ultraviolet diffraction

IG Pallares, D Rout, TJ Deering… - ACS Applied Nano …, 2020 - ACS Publications
The fabrication of highly ordered∼ 2 μm thick silica inverse opal (IO) photonic crystal (PhC)
films is reported. These IO films diffract deep ultraviolet light (UV,< 250 nm) and are …
