Abstract :
Simulation and experimental measurements are presented for 60 GHz transmission systems based on upconversion. We demonstrate that chirp in modulated semiconductor lasers combined with upconversion allows to realize a simple system resistant to chromatic dispersion without the need for customized filter. The comparison between two 60 GHz modulation schemes highlights the possibility to reduce power fading, due to chromatic dispersion, to a value as low as optical fiber attenuation.
