Dd. Marcenac et Je. Carroll, DISTINCTION BETWEEN MULTIMODED AND SINGLEMODED SELF-PULSATIONS IN DFBLASERS, Electronics Letters, 30(14), 1994, pp. 1137-1138
DFB lasers with split contacts are shown, by large signal dynamic mode
lling, to self-pulsate at gigabit frequencies. Two different self-puls
ation schemes are discussed: where the laser switches between the high
er and lower stop band modes, and where the laser pulsates around a si
ngle mode. The second scheme can yield self-pulsation frequencies beyo
nd 20GHz. Comparisons are made with experimental results.
