Abstract

We have experimentally demonstrated the transmission performance of a feedforward optical transmitter using an external light injection technique. The feedforward compensation method shows 31 dB intermodulation distortion suppression and 2.2 dB noise reduction. A high side-mode suppression ratio (SMSR) exceeding 35 dB of the wavelength-locked FP-LD was obtained over 12 nm ranges. The suppression characteristics of the intermodulation distortion for wavelength differences and various transmission lengths were measured and analyzed as the evaluation criteria for the transmission performance in WDM/SCM based radio-over-fiber systems.
