Abstract

A formation is presented to study the effect of carrier heating on the second-order harmonic distortion of semiconductor lasers under analogue-amplitude modulation. The results show that the second-order harmonic distortion will be enhanced by the effect of dynamic carrier heating if the modulation frequency is much smaller or much larger than the resonant frequency. On the other hand, it will be suppressed by the effects of dynamic carrier heating if the modulation frequency is close to the resonant frequency. For a typical carrier energy relaxation time within 0.5-2 ps, the results indicate that the effect of dynamic carrier heating alone on the second-order harmonic distortion may be insignificant. The results also suggest that the effect of dynamic carrier heating on the second-order harmonic distortion can become important if the carrier energy relaxation time or the dc bias current are enormously large.
