Measuring sub-Planck structural analogues in chronocyclic phase space
Dane R. Austin, Tobias Witting, Ian A. Walmsley
The phase space structure of certain quantum states reveals structure on a scale that is small compared to the Planck area. Using an analog between the wavefunction of a single pho…

Ultrashort pulse characterization by spectral shearing interferometry with spatially chirped ancillae
Tobias Witting, Dane R. Austin, Ian A. Walmsley
We report a new version of spectral phase interferometry for direct electric field reconstruction (SPIDER), which enables consistency checking through the simultaneous acquisition…
