Abstract
Abstract The generation of 80 GHz millimeter wave (mm-wave) signal and its transmission over single mode fiber (SMF) is presented. The mm-wave signal is generated with dual parallel dual drive Mach Zehnder modulators using frequency quadrupling of 20 GHz radio frequency signal. Transmission of generated mm-wave signal over SMF has been investigated. The impact of varying modulation depth on optical side band suppression ratio and radio frequency spurious suppression ratio for different extinction ratios (ER) is studied. Further, the impact of dispersion, on received power is also analyzed. Error analysis between analytical and simulation results is carried out. It has been observed, that increasing ER leads to reduction in both peak error and mean error and the received power is reduced under the combined effect of second and third order dispersion at very high modulation depth.
