| Abstract: | A 120-GHz millimeter-wave system using two lasers and two Mach–Zehnder modulation (MZM) with frequency 8-tupling of the radio frequency local oscillator’s signal frequency is proposed and demonstrated. The first MZM is the even-order harmonic modulations output and then optical filter filters the 0-order wave. The second MZM is the single sideband suppression output. In the system, two light components with the same phase noise are generated. The millimeter wave can avoid the laser phase noise. It has simplified the system, so the fibre dispersion is reduced. |
