By employing the self-modulation birefringence difference in a semiconductor optical amplifier (SOA), an improved method is proposed to generate a complete optical single-sideband (OSSB) signal. Over sideband suppression ratios (SSRs) of lower OSSB signals are obtained over a input power range and a wavelength span, with a maximum of over . Upper OSSB signals with an SSR of over are observed using a SOA for what is believed to be the first time. This method is effective even for the carrier-suppressed signal. The theory for OSSB generation in an SOA is extended and verified by experiment.
