Abstract
We show a concept of optical frequency tweezers for tweezing light in the optical frequency domain with a high resolution, which is the frequency version of optical tweezers for the spatial manipulation of microscopic objects. We report a proof-of-principle experiment via frequency conversion inside a cavity only for the converted light. Owing to the atypical configuration, the experiment successfully achieves the tweezing operation in the frequency domain, which picks light at a target frequency from the frequency-multiplexed input light and converts it to a different frequency, without touching any other light sitting in different frequency positions and shaking the frequency by the pump light.
