Abstract

We proposed single-sideband (SSB) quadrature phase-shift keying (QPSK) vector radio-frequency optical signal generation enabled by a single directly modulated laser without precoding technology, which can reduce the system cost and tolerate fiber dispersion. Based on our proposed scheme, we experimentally demonstrated 8-Gbaud SSB QPSK signals generation at 10 GHz, and the generated signals are transmitted over 50-km single-mode fiber without power penalty. Our experimental results show that an equal power SSB signal can tolerate fiber dispersion and have the highest receiver sensitivity.
