Description

technical field [0001] The invention relates to the technical field of frequency conversion processing of wireless signals, in particular to a multi-channel frequency conversion structure realized by polarization state independent modulation. Background technique [0002] In modern communication, microwave signal processing is a key technology in electronic systems such as radar and satellite. However, in the development of the electric field, limited by electronic devices, microwave frequency conversion technology has problems such as limited bandwidth, small frequency tunable range, poor isolation, and serious electromagnetic interference. Using photon technology to process microwave signals can complete functions and indicators that cannot be realized in the electrical domain. Among them, microwave photonic frequency conversion technology combines the advantages of high resolution and high flexibility of microwave, and performs frequency conversion and signal processing ...
