The word "transformational" is often used to describe potentially exciting new research, but rarely does the research live up to the hype. Rydberg probes, based upon work principally developed by the U.S. National Institute of Standards and Technology (NIST), may very well be the exception.

NIST’s Communications Technology Lab is developing a new paradigm for RF field sensing and measurements based on the atom. The Rydberg Atom-based RF Field Probes team is using highly excited alkali atoms to detect and measure electric fields from DC to daylight (from Hz to THz) with high sensitivity and fidelity. Due to the standard behavior of these atoms, this independent RF measurement method provides direct traceability to SI-defined constants.

NIST is currently exploring the use of Rydberg probes for:

  • Fundamental RF Field Metrology – Atom-based microwave field measurements are independent of the traditional calibration method. We are exploring the extent to which Rydberg atom-based field probes can improve field probe calibrations and push the limits of RF field metrology.
  • RF Camera – Formed from an array of Rydberg sensors, the RF camera will be able to measure the magnitude and phase of an RF field at multiple points in a low-invasive package that reduces distortion of the field.
  • Communications Reception – the Rydberg atoms can act as electrically small antennas and detect the modulation of a carrier wave. They can detect and demodulate AM, FM, and phase modulation over a broad range of carrier frequencies – making them a promising platform for advanced communication receivers.
  • Blackbody Radiation Characterization – Highly excited Rydberg atoms are very sensitive to external fields and can sense changes in thermal radiation. We have a project to explore the limit of using Rydberg spectroscopy to measure and calibrate blackbody radiation.
  • DC/AC Voltage Standards – We are exploring the application of atom-based field measurements to DC – kHz voltage measurements to provide less expensive self-calibrated, SI-traceable voltage standards.
  • RF Power Metrology – We have two methods for advanced RF power metrology, using both Rydberg atom measurements as well as photon pressure. These two methods can span a much larger dynamic range of traceable power measurements, from nW – kW, than traditional calorimeter-based measurements.

Please join NIST's Dr. Christopher Holloway speaking about NIST's work on Rydberg probes and the commercialization challenges and opportunities of this exciting new technology. Dr. Holloway will also take questions on his work. 

WInnForum CTO Dr. Andrew Clegg will host this first in an occasional series of WInnForum Webinars on today's most promising Wireless Innovations. This Webinar will be held on 20 September, 10am PT/1pm ET - 11:30am PT/230 pm ET (90 minute webinar).
