Theoretical Analyses

In this paper, a approach for frequency 12-tupling millimeter-wave generation using one DPMZM (Dual-Parallel Mach-Zehnder Modulator) to overcome chromatic dispersion is demonstrated. The millimeter-wave with the baseband signal carried only by minus 6-th order sideband is generated by properly adjusting a series of parameters. As the signal transmittes along the fiber, there is no time shift caused by chromatic dispersion. Theoretical analyses and simulated results show that when the optical mm-wave carrying 2.5Gbps baseband signal transmits over 55 Km, the eye diagram still keeps open and clear. The power penalty is about 0.7 dB after transmits over 40 Km.
