In this Letter, we report a chip-based photonic radio-frequency (RF) mixer with a maximum conversion gain of -9 and image rejection ratio of 50 dB for 3.2 GHz to 13.2 GHz RF frequency range. This is achieved by the combined use of optical carrier suppression modulation and on-chip stimulated Brillouin scattering. These results will stimulate future implementations of integrated photonic RF mixers in complicated electromagnetic environments.
在本信函中，我们报道了一种基于芯片的光子射频（RF）混频器，在3.2吉赫兹至13.2吉赫兹射频频率范围内，其最大转换增益为-9，镜像抑制比为50分贝。这是通过光载波抑制调制和片上受激布里渊散射的联合使用实现的。这些结果将推动集成光子射频混频器在复杂电磁环境中的未来应用。
