Abstract

Frequency deviations in a regime of high rate current fluctuations in distributed feedback (DFB) and grating coupler sample reflector (GCSR) lasers are measured using novel statistical frequency discrimination technique. Thermal time constants of the order of nanoseconds are observed in both.
