Type: article
Abstract: A novel system to generate and transmit frequency 16-tupling millimeter waves (MMWs) without the bit walk-off effect created by the Mach–Zehnder modulator (MZM) is proposed. The ±8th-order sidebands are generated by four MZMs connected in parallel with the data carried only on the +8th-order sideband by adopting the composite radio frequency (RF) for the MZMs. The frequency 16-tupling MMW with data is generated by injecting the ±8th order sidebands into the photodetector. The system’s principle of operation is given. The feasibility of our designed schemes is verified by the simulation experiment. The effect on the system’s BER is discussed when the main parameters diverge from their theoretical values or default values. Our designed system can effectively eliminate the bit walk-off effect caused by fiber dispersion and greatly raise the fiber distribution distance.
