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
