Abstract

We propose and experimentally demonstrate a novel photonic scheme to generate differential-phase amplitude-shift keying (DPASK) or circular quadrature amplitude modulation (QAM) signal at microwave/millimeter-wave band for Radio-over-Fiber applications. In our proposed scheme, the electronic driven circuits are greatly simplified by employing photonic vector modulation technique in which only an electro-optical phase modulator and two Mach-Zehnder modulators are needed.
