All-optical format conversion plays an important role in future transparent optical networks in order to enhance reconfigurability. On the other hand, the polarization-division multiplexing (PDM) technique has been extensively studied for achieving high-speed and high-spectral-efficiency optical networks. Since the state of polarization of PDM signals are randomly changed along the transmission optical...
We experimentally demonstrate polarization-division-multiplexing quadrature-phase-shift-keying (PDM-QPSK) modulated vector signal generation at the W-band, adopting Mach–Zehnder-modulator-based (MZM-based) photonic frequency octupling and phase precoding techniques. The MZM biased at its maximum transmission point is driven by a 12-GHz precoded vector signal, which is generated by MATLAB programming...
