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