99% beta factor and directional coupling of quantum dots to fast light in photonic crystal waveguides determined by hyperspectral imaging
L. Scarpelli, B. Lang, F. Masia +8
Spontaneous emission from excitonic transitions in InAs/GaAs quantum dots embedded in photonic crystal waveguides at 5K into non-guided and guided modes is determined by direct hyp…

Ultrafast tuneable optical delay line based on indirect photonic transitions
Daryl M. Beggs, Isabella H. Rey, Tobias Kampfrath +3
We introduce the concept of an indirect photonic transition and demonstrate its use in a dynamic delay line to alter the group velocity of an optical pulse. Operating on an ultrafa…

Ultrafast tilting of the dispersion of a photonic crystal and adiabatic spectral compression of light pulses
Daryl M. Beggs, Thomas F. Krauss, L. Kuipers +1
We demonstrate, by theory and experiment, the ultrafast tilting of the dispersion curve of a photonic-crystal waveguide following the absorption of a femtosecond pump pulse. By sha…
