Optical millimetre-wave generation and transmission experiments for mobile 60 GHz band communications
Experiments on the optical generation and transmission of millimetre-wave radio signals are reported. the millimetre-wave carrier is generated by hetrodyning the signals of two semiconductor lasers at an optic/millimetre-wave converter. A 140 Mbit/s signal at a carrier frequency beyond 60 GHz was transmitted successfully with a BER below 10-9.
