Abstract :
The authors present the idea of using a laser with improved modulation bandwidth to generate microwave optical signals for hybrid radio/fibre systems. External light injection has been used to enhance the frequency response of the laser and thus greatly improve the overall performance of the hybrid system. Experimental results show an 8 dB improvement in system performance for the externally injected laser in a hybrid radio/fibre system used for distributing 155 Mbit/s data signals on an 18 GHz carrier
