Measurements of thermal frequency chirp in directly modulated DFB lasers and thermal transient induced frequency drift during fast tuning in GCSR lasers using frequency discrimination technique Conference Paper uri icon


  • 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.
