Optical frequency conversion is an indispensable technology in modern science and engineering. In particular, recent demand in the field of quantum information processing requires an efficient frequency conversion of a single photon which has quantum information [1], [2] for realizing quantum internet to interconnect various quantum systems. In conventional experiments, such a quantum frequency conversion (QFC) assumes an input of photons at a single frequency mode. However, when we look at frequency-multiplexed quantum communication [3], [4], the QFC will need to accommodate the frequency-multiplexed manner such that it can convert only photons in a target frequency mode from densely frequency-multiplexed input to any desired frequency mode. For this purpose, we construct an optical frequency converter inside a cavity only for the converted mode, which we call optical frequency tweezers [5].
