Description
Summary:Nonlinear magnetoelectric effect(NME) in alkali atomic vapor has applications in precision magnetometry in the radio-frequency domain. We report the application of the NME in alkali atomic vapors for projective measurement of medium-frequency (MF) magnetic fields in a circular basis with an extinction ratio up to 500:1 . Utilizing a longitudinal static magnetic field, we demonstrate a high-sensitivity technique for characterizing the ellipticity of radio-frequency (RF) magnetic fields which can in turn be used for phase sensitive detection in mid frequency communication. Additionally, we demonstrate the conversion of binary phase shift keyed RF magnetic fields into amplitude modulation of generated optical fields, a versatile receiver for communication using the medium frequency band.
