Abstract— A In this paper the authors have theoretically investigated the transmission performance of the optical millimeter (mm)-wave generated by a structure of optical modulation dedicated to Radio-over-Fiber (RoF) system. This configuration generates optical 16-QAM signals in a quad-parallel structure of Mach-Zehnder modulators (MZMs) producing the 60 GHz mm-wave after passing through the bandpass filter centered on this frequency. The millimeter-wave is obtained with optical frequency multiplication. Clear eye opening was achieved at 20 Gbaud with on-off-keying, in order to prove that the evidence that the 60 GHz RoF structure suggested is successful. Such a system can be appropriate for the proposed coherent optical/wireless seamless network.
