• A novel bidirectional lightwave transport system is proposed and demonstrated.
• We employ PM scheme and injection-locked DFB LD as a duplex transceiver for PON.
• We employ laser pointer lasers with directly modulating data signals for WDM VLC.
• Impressive results prove the proposed system is shown to be a distinguished one.
• To present its simplicity in PON integration with VLC application.

A novel bidirectional lightwave transport system employing phase modulation (PM) scheme and light injection-locked distributed feedback laser diode (DFB LD) as a duplex transceiver for passive optical network (PON); as well as employing laser pointer lasers (LPLs) with directly modulating data signals for wavelength-division-multiplexing (WDM) visible light communication (VLC) is proposed and experimentally demonstrated. Impressive and low bit error rate (BER) operation is achieved for PON integration with VLC application. Such bidirectional PON integration with VLC system has been successfully demonstrated, which can not only present its advancement in PON/VLC application but also reveal its simplicity and convenience to be installed. Whereby, our proposed system is suitably applicable to the PON in combination with VLC system in wire and wireless transmission.
