VHF/UHF detection using high angular momentum Rydberg states
We demonstrate resonant detection of rf electric fields from 240 MHz to 900 MHz (VHF/UHF) using electromagnetically induced transparency with orbital angular momentum, L = 3 → L′ = 4, Rydberg states. These Rydberg states are accessible with three-photon infrared optical excitation. By reducing the rf carrier frequency from the gigahertz range, these Rydberg states enable a broader class of electrically small atomic receivers. We assess sensitivity limits and prospects for further reduction of on-resonant carrier frequencies.
