Optical Push Broom On a Chip
Mahmoud A. Gaafar, He Li, Xinlun Cai +3
Here we report the first experimental demonstration of light trapping by a refractive index front in a silicon waveguide, the optical push broom effect. The front generated by a fa…
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…
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…
Charging of Superconducting Layers and Novel Type of Hysteresis in Coupled Josephson Junctions
Yu. M. Shukrinov, Ma. A. Gaafar
A manifestation of a novel type of hysteresis related to the parametric resonance in the system of coupled Josephson junctions is demonstrated. Opposite to McCumber and Steward hys…
