Abstract
In two experimental hybrid fiber radio systems the millimeter-wave carriers for the radio links at 40 and 60 GHz were remotely generated by optical heterodyning. In the first experiment at 40 GHz the optical source was a dual-mode self-pulsating laser while in the second experiment at 60 GHz separate single-mode lasers were used which were stabilized by optical injection locking. Within both experiments error-free 155 Mbit/s data transmission was achieved. At 60 GHz the far field was steered using a twin-waveguide antenna configuration.
