Abstract :
1.3 /spl mu/m strained-layer multi-quantum well distributed-feedback (SL-MQW-DFB) lasers with low distortion characteristics over wide frequency range even at high optical output power operation have been successfully fabricated. This is achieved by both the high relaxation oscillation frequency characteristics of the SL-MQW active structure and the suppression of non-radiative current in the relatively long laser cavity. By using the laser as a light source for CATV transmission system, high quality AM-FDM transmissions with the largest channel capacity (151ch) have been demonstrated.<>
