The mode division multiplexing (MDM) signal transmitted in an optical multimode fibre link is usually received with multiple coherent receivers (RXs), resulting in an increase in RX system scale. A mode‐selective coherent detection technique is proposed based on MDM‐to‐frequency division multiplexing (FDM) signal conversion scheme using an MDM and FDM local oscillator. The proposed technique uses only a single coherent RX to detect the MDM signal to achieve low‐complexity MDM systems. The proposed mode‐selective coherent detection technique is also experimentally shown. The experimental results show that a single coherent RX successfully receives the MDM signal.
