Abstract :
Simultaneous 60-GHz radio over fiber upconversion and fiber transmission of lightwaves produced by an external cavity laser, a distributed feedback laser, and a C-band vertical cavity surface emitting laser are demonstrated. The 1.25-Gb/s data are transmitted concurrently on each of the lightwaves attaining a bit error rate performance <10-9 level. Carrier suppression of 20 dB is achieved for all three lightwaves placed in a wide wavelength range. The 10-9 receiver sensitivity level for detection of three lightwaves falls in a <3-dB region. Reported close performance of the investigated techniques enables diversification of options for lightwave generation in millimeter-wave fiber-wireless networks.
