We propose and demonstrate a modulation transfer protocol to increase the detection sensitivity of a Rydberg RF receiver to fields out of resonance from the transition between Rydberg levels. This protocol is based on a phase modulation of the control field used to create the Electromagnetically Induced Transparency signal. The nonlinear wave mixing of the multi-component coupling laser and the probe laser transfers the modulation to the probe laser, which is used for the RF-field detection.

1 INTRODUCTION There is an ever-increasing awareness of climate change and its impacts, especially since the publication of the IPPC Climate Change 2021 Report,1 which states that “in the next 20 years, global temperatures are expected to reach or exceed 1.5° C of warming”.1 Hence there is a significant need for a large-scale reduction in greenhouse gas emissions. One contributory solution is the modal shift from road to rail, particularly within freight.
