AB - We report a broadband microwave frequency converter based on a coherent Kerr optical micro-comb generated by an integrated micro-ring resonator. The coherent micro-comb displays features that are consistent with soliton crystal dynamics with an FSR of 48.9-GHz. We use this to demonstrate a high-performance millimeter-wave local oscillator at 48.9-GHz in the Q-band for microwave frequency conversion. We experimentally verify the microwave performance up to 40 GHz, achieving a ratio of −6.8 dB between output RF power and IF power and a spurious suppression ratio of > 43.5 dB. The experimental results show good agreement with theory and verify the effectiveness of microwave frequency converters based on coherent optical micro-combs, with the ability to achieve reduced size, complexity, and potential cost.

INTRODUCTION icrowave frequency conversion for signal transmission or processing is a key processing block in radio-over-fibre (RoF) systems, beamforming and radio frequency communication networks [1-4]. As compared with electrical approaches that are subjected to the electrical bandwidth bottleneck [5, 6], photonic microwave frequency converters [7-9] could offer many competitive advantages including large bandwidth, high isolation, and strong immunity to electromagnetic interference, and so are promising solutions to meet with
