Abstract

We have achieved optical frequency conversion based on secondary optical nonlinearity using a resonator that is pre-resonated only to the desired converted frequency. This new frequency converter has many advantages over traditional frequency converters [1].

Singly Resonant Frequency Conversion for Manipulation of a Frequency-Multiplexed Single Photon

Rikizo Ikuta, Masayo Yokota, Toshiki Kobayashi +2 more

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].

Channel-selective frequency up-conversion for frequency-multiplexed quantum network

Shoichi Murakami, Shunsuke Hiraoka, Toshiki Kobayashi +2 more

We demonstrate channel-selective frequency up-conversion from telecom wavelengths around 1540 nm for optical fiber communication to visible wavelengths around 780 nm, based on second-order optical nonlinearity in a cavity of the converted modes. In our experiment, we selectively convert a light from any frequency mode within frequency-multiplexed telecom signals to a desired output mode, determined by the cavity resonances. Based on the experimental results of the frequency up-conversion, we derive the signal-to-noise ratio of the process at the single-photon level, and discuss its applicability to channel-selective quantum frequency conversion (CS-QFC) in the context of frequency-multiplexed quantum networks. Finally, we describe specific use cases of the CS-QFC, which show its utility as a reconfigurable switching element in frequency-multiplexed networks, particularly for selectively performing Bell-state measurements between two photons originating from different frequencies.

On-chip ultra-broad frequency conversion via simultaneous second and third-order optical nonlinearity

Steven A. Miller, Kevin J. Luke, Yoshitomo Okawachi +3 more

We demonstrate ultra-broad frequency conversion through simultaneous second and third-order nonlinearities. Using a high-Q resonator, we generate multiple frequency lines in both the near-IR and in the visible range using a single near-IR CW pump.

Quantum frequency conversion

An experimental scheme is proposed by which the quantum states of two light beams of different frequencies can be interchanged. With this scheme it is possible to generate frequency-tunable squeezed light for spectroscopic applications.

High conversion efficiency in resonant four-wave mixing processes

Chin-Yuan Lee, Bo-Han Wu, Gang Wang +3 more

We propose a new scheme of the resonant four-wave mixing (FWM) for the frequency up or down conversion, which is more efficient than the commonly-used scheme of the non-resonant FWM. In this new scheme, two control fields are spatially varied such that a probe field at the input can be converted to a signal field at the output. The efficiency of probe-to-signal energy conversion can be 90% at medium's optical depth of about 100. Our proposed scheme works for both the continuous-wave and pulse cases, and is flexible in choosing the control field intensity. This work provides a very useful tool in the nonlinear frequency conversion.
