Abstract

Material growth optimization of InAs/InP quantum dashes has allowed the achievement of single section mode-locked lasers with improved performance in terms of modal gain >; 40 cm^-1, average output power >; 40 mW, radio frequency linewidth as narrow as 10 kHz together with a direct modulation bandwidth over 7 GHz. These devices were subsequently investigated as potential optical transmitters for mm-wave generation, namely 60 GHz radio-over-fiber applications. Relatively low error vector magnitude errors of ~ 11 % as well as high extinction ratio >; 25 dB shows the potential of these devices for >; 2.5 Gb/s short distance indoor communications.
