Abstract
The longitudinal mode hopping and the related terminal electrical noise
in InGaAs/GaAs ridge single quantum well (SQW) lasers are investigated.
It is found that electrical mode hopping has a Lorentzian dependence.
The correlation with the optical noise is experimentally shown in the
low-medium frequency range. Measurements of this electrical-optical
correlation give a high value of this parameter (
)
when the longitudinal mode hopping is present.
