# schematic of the optical frequency combs experimental setup

## Appears In

                        - Detangling Light-based Thermometers with Combs

A schematic of the experimental setup. Laser light is manipulated to create two optical frequency combs (colored green and blue here, though they both use infrared light in the experiment). The light from the frequency combs is combined to create light with a beat pattern. This light is split into two: Some of it goes into the sensor, sitting in a thermal bath that subjects it to a well-controlled temperature, and the rest goes into an RF detector used as a reference. Finally, light carrying the information about temperature is reflected back out of the sensor and collected by an RF detector.
