Dual-mode radio frequency reception based on Electro-Opto-Mechanics

Abstract

Cavity electro-opto-mechanical (EOM) systems enable the microwave-optical interaction via the mechanical intermedia. By driving the electromechanical and optomechanical beam splitter interactions simultaneously, the EOM system can coherently convert the photons between microwave and optical domains bidirectionally. Here, we use this property to study a tunable dual-mode radio frequency reception, which is achieved by coherent frequency up-conversion in a two-mechanical-mode EOM system, and signal processing in an all-optical manner. A comprehensive design of EOM based dual-mode radio frequency receiver is proposed and demonstrated. We systematically analyze the realization of dual-mode radio frequency reception and verification of the dual-mode tunability. The results suggest well performance in tunable dual-mode frequency up-conversion and noise suppression. In addition, it also shows the advantages in low-power consumption, miniaturization, and massive on-chip integration. Given the latest advances on cavity electro-opto-mechanics, our scheme is feasible and can be extended to tunable multichannel multimode radio frequency reception.
