Influences of noise on the occurrence of period doubling in distributed-feedback laser diodes under direct-current modulation.
The influences of Langevin noise on period doubling (PD) of a strongly modulated distributed-feedback laser have been investigated. The onset of PD was confirmed to be reduced through the use of the rate equations as a model. The threshold values of PD were examined in terms of driving frequency and rf power and have been compared with the measurements of PD.
