The limits for complete photonic bandgaps in low-contrast media
Lukas Maiwald, Timo Sommer, Marvin Schulz +2
The minimal refractive index contrast to obtain a complete photonic bandgap (CPBG) in structured media was not identified so far. We address this problem by considering distributed…
Ewald sphere construction for structural colors
Lukas Maiwald, Slawa Lang, Dirk Jalas +3
Disordered structures producing a non-iridescent color impression have been shown to feature a spherically shaped Fourier transform of their refractive-index distribution. We deter…
Photonic glass for high contrast structural color
Guoliang Shang, Lukas Maiwald, Hagen Renner +5
Non-iridescent structural colors based on disordered arrangement of monodisperse spherical particles, also called photonic glass, show low color saturation due to gradual transitio…
A quantitative first-order approach for the scattering of light by structured thin films
Slawa Lang, Lukas Maiwald, Hagen Renner +3
We present a full vectorial first-order approach to the scattering by arbitrary photonic structures with a low refractive index contrast. Our approach uses the first-order Born app…
