AJ Fleisher (right) and Tobias Herman (left) with the experimental setup. A laser produces light that is manipulated on the table to create two optical frequency combs. The light from these combs is combined and fed into the fiber optic cable that contains the photonic sensor, which is located inside a well with a controlled temperature. Finally, the light signal is read by RF detectors. Credit: Jennifer Lauren Lee/NIST. |
