Frequency Shifted Optical SSB Modulation Scheme and Its Application to SCM Transmission

Abstract

We propose frequency shifted optical single sideband (OSSB), a novel OSSB modulation scheme. It uses a continuous wave to up-convert the source signal, and the signal and the continuous wave then undergo suppressed carrier OSSB modulation simultaneously. This scheme inherently has no unwanted sidebands, even if the suppressed carrier OSSB modulator is defective. Experiments of 12GHz RF signal transmission confirm that it achieves 2.4dB relaxation in chromatic dispersion power fading under the condition of 15dB SSR.
