Paper Abstract

In this work, we propose and investigate a novel modulation technique for the generation of multiple millimeter wave (mm-wave) signals using high-order harmonic generation with a dual-electrode Mach-Zehnder modulator (MZM). The laser output is split into two branches by the use of a polarization beam splitter. We use polarization multiplexing to avoid the inter-symbol interference between multiple mm-wave signals. The proposed technique is comprised of two parallel MZMs. As an example, we consider an RF1 at 7.5 GHz and RF2 at 8.125 GHz, each of which carries its own data signal and drives each MZM, respectively; and mm-wave signals at 30 GHz and 32.5 GHz, i.e. a frequency quadrupler, are obtained after photomixing. The performance of the system is evaluated in terms of Q-factor. Simulation results show that data signal at 625 Mb/s is successfully transmitted over 50 km of single mode fiber. The generated mm-wave signal is robust to chromatic dispersion.
