Low-cost adaptive directly modulated optical OFDM based on semiconductor optical amplifier
Low cost optical OFDM has great potential for next generation optical access networks and PONs. Optical OFDM has high flexibility in bandwidth manipulation, and high spectral efficiency. We propose adaptive direct modulation of semiconductor optical amplifier. New adaptive current loading techniques for PAPR reduction are proposed and analyzed.
