Light Confinement and Nonlinear Light-Matter Interaction in Semiconductor Photonic Crystal Cavities

Mohamed Sabry Abdel-Aliem Mohamed

The ability to control and manipulate light is a fundamental aspect that is at the very core of the development of integrated photonic circuits. It is desirable to achieve such control down to a scale that is comparable to or smaller than the wavelength of ...

Efficient continuous-wave nonlinear frequency conversion in high-Q gallium nitride photonic crystal cavities on silicon

Romuald Houdré, Nicolas Grandjean, Jean-François Carlin, Vincenzo Savona, Matteo Galli, Momchil Minkov, Mohamed Sabry Abdel-Aliem Mohamed

We report on nonlinear frequency conversion from the telecom range via second harmonic generation (SHG) and third harmonic generation (THG) in suspended gallium nitride slab photonic crystal (PhC) cavities on silicon, under continuous-wave resonant excitat ...

Ultra-wide-band structural slow light

Romuald Houdré, Vincenzo Savona, Momchil Minkov, Mohamed Sabry Abdel-Aliem Mohamed

The ability of using integrated photonics to scale multiple optical components on a single monolithic chip offers key advantages to create miniature light-controlling chips. Numerous scaled optical components have been already demonstrated. However, presen ...

Influence of Disorder and Finite-Size Effects on Slow Light Transport in Extended Photonic Crystal Coupled-Cavity Waveguides

Romuald Houdré, Vincenzo Savona, Momchil Minkov, Mohamed Sabry Abdel-Aliem Mohamed

A convenient approach for slowing down light in integrated optical circuits is by utilizing a set of coupled microcavities in a photonic crystal lattice. While this provides for flexibility in dispersion engineering, light transport is influenced by a comb ...
