1. A system for measuring radio frequency (RF) electromagnetic waves, the system comprising:
a laser system configured to generate a plurality of input optical signals;
an RF measurement device comprising:
first and second mode converters, each configured to convert a mode of an RF electromagnetic wave between a first RF waveguide mode and a second RF waveguide mode,
an internal cavity between the first and second mode converters and containing a vapor that is configured to produce an output optical signal based on the plurality of input optical signals, the vapor comprising Rydberg atoms or molecules, and
an RF waveguide extending between the first and second mode converters and configured to carry the second RF waveguide mode through the internal cavity;
an optical detector system configured to generate a detector signal in response to receiving the output optical signal, the detector signal representing an optical property of the output optical signal; and
a signal processing system configured to generate data in response to receiving the detector signal, the data representing a property of the RF electromagnetic wave.
