Photonic vector signal generation at W-band employing an optical frequency octupling scheme enabled by a single MZM

• We propose photonic vector signal generation at microwave/mm-wave bands enabled by a single MZM and phase-precoding technique, which can realize photonic frequency octupling (×8) multiplication of the precoded microwave vector signal used for the drive of the single MZM.
• We also experimentally demonstrate photonic QPSK-modulated vector signal generation at W-band adopting photonic frequency octupling (×8) based on our proposed scheme. The MZM is driven by a 12-GHz QPSK modulated precoded vector signal, the phase of which is one eighth of the phase of the regular QPSK signal.
• The generated 4-Gbaud QPSK modulated electrical vector signal at 96 GHz can realize 3-m wireless delivery with a BER less than the HD-FEC threshold of 3.8×10−3.

We propose photonic vector signal generation at millimeter-wave (mm-wave) bands enabled by a single Mach–Zehnder modulator (MZM) and phase-precoding technique, which can realize photonic frequency multiplication of the precoded microwave vector signal used for the drive of the single MZM. We also experimentally demonstrate the generation of quadrature-phase-shift-keying (QPSK) modulated vector signal at W-band adopting photonic frequency octupling (×8) based on our proposed scheme. The MZM is driven by a 12-GHz QPSK modulated precoded vector signal. Up to 4-Gbaud QPSK-modulated electrical vector signal at 96 GHz is generated and then delivered over 3-m wireless transmission distance.
