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

Published in IOP Quantum Science and Technology, 2025

Key results from the phase modulation paper, showing the phase shift and transmission for various signal detunings. Left panels show experiment, and right panels show simulations.

We achieve a phase modulation of 90(5)% of pi via a two-photon transition in Rb vapour.
