Fourier optics with linearly tapered waveguides: light trapping and focusing
Mahmoud A. Gaafar, Hagen Renner, Manfred Eich +1
An optical pulse asymptotically reaching zero group velocity in tapered waveguides can ultimately stop at a certain position in the taper accompanied by a strong spatial compressio…
Linear Schrödinger equation with temporal evolution for front induced transitions
Mahmoud A. Gaafar, Hagen Renner, Alexander Y. Petrov +1
The nonlinear Schrödinger equation based on slowly varying approximation is usually applied to describe the pulse propagation in nonlinear waveguides. However, for the case of the…
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…
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…
