Abstract

Microwave photonic frequency conversion and transmission is highly needed in modern distributed communication systems. However, the periodically power fading and co-frequency interference limits the working frequency range, transmission distance, and the number of channels. To address the above questions, a novel dual-channel microwave photonic frequency conversion and transmission method is proposed. A DPol-DPMZM modulator is applied and the dual-channel intermediate frequency (IF) signals and the local oscillator (LO) signal are both applied to the DPol-DPMZM modulator to produce optical sidebands of IF and LO signals. Through the jointly manipulate phase of optical sidebands, the periodically power fading and co-frequency interference problems can be simultaneously addressed, which guarantees the broadband and multi-channel performance of microwave photonic frequency conversion and transmission system.
