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…
Reciprocity approach for calculating the Purcell effect for emission into an open optical system
K. M. Schulz, D. Jalas, A. Y. Petrov +1
Based on the reciprocity theorem, we present a formalism to calculate the power emitted by a dipole source into a particular propagating mode leaving an open optical system. The op…
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…
Emission enhancement in dielectric nanocomposites
Dirk Jalas, K. Marvin Schulz, Alexander Petrov +1
We consider emitting nanoparticles in dielectric nanocomposites with varying refractive index contrast and geometry. For that we develop a simple and universal method to calculate…
Highly effective relativistic free carrier plasma mirror confined within a silicon slow light photonic crystal waveguide
Mahmoud A. Gaafar, Dirk Jalas, Liam OFaolain +4
Reflection at relativistically moving plasma mirrors is a well-known approach for frequency conversion as an alternative to nonlinear techniques. A key issue with plasma mirrors is…
Comment on "Linear and passive silicon optical isolator" in Scientific Reports 2, 674
Alexander Petrov, Dirk Jalas, Manfred Eich +10
Wang et al. [1] demonstrated different power transmission coefficients for forward and backward propagation in simulation and experiment. From such a demonstration, the central cla…
Comment on "Nonreciprocal Light Propagation in a Silicon Photonic Circuit" in Science 333, 729-733 (2011)
Alexander Petrov, Dirk Jalas, Manfred Eich +4
In the recent article by Feng et al. [Science 333, 729-733 (2011)] a system is proposed with a periodic spatial modulation of refractive index and absorption. It is claimed that th…
