Laser-Phase-Fluctuation-Insensitive Optical Coherent Transmission of 16-Quadrature-Amplitude-Modulation Radio-Over-Fiber Signal

A laser-phase-fluctuation-insensitive optical coherent transmission of a 10-Gbaud 16-quadrture-amplitude-modulation radio-over-fiber signal with an offset-frequency-spaced two-tone local light and an digital-signal-processing technique is experimentally demonstrated. Error-free symbol recovery after the 20-km-long fiber-optic transmission is shown and the transmission quality is evaluated.
