Abstract

In this paper we demonstrate the detection of millimeter waves via Autler-Townes splitting in 85Rb Rydberg atoms. This method may provide an independent atomic-based SI-traceable method for measuring mm-wave electric fi elds, which addresses a gap in current calibration techniques in the mm-wave regime. The electric field amplitude within a rubidium vapor cell in the WR-10 wave guide band is measured for frequencies of 93 GHz, and 104 GHz. Relevant aspects of Autler-Townes splitting originating from a four-level electromagnetically induced transparency scheme are discussed. Experimental results are presented where we measure the E-fi eld generated by an open ended wave guide using this technique. Experimental results are compared to a full wave finite element simulation.
