High-conversion-gain and deep-image-rejection Brillouin chip-based photonic RF mixer

Abstract

In this Letter, we report a chip-based photonic radio-frequency (RF) mixer with a maximum conversion gain of − 9 d B 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.
