Data supporting "Fast, low-loss, all-optical phase modulation in warm rubidium vapour"

This dataset includes data that describes phase modulation of light mediated by an all-optical, two-photon transition in warm rubidium vapour. The presence of a bright control field, detuned from an atomic resonance, induces a change in the atomic susceptibility. A weak signal field counter-propagates with the control field, and experiences phase modulation, which is dependent on the strength intensity of the control field. These data are collected from experiments in both a continuous wave and pulsed field configuration. We also include numerical simulations of the continuous wave experiments.
