| Popis: | It is shown that for an average output power of 60 mW, the spectral density of low-frequency intensity fluctuations in single-mode semiconductor lasers lies in the interval 6 ? 10-17 ? 10-15 W2 Hz-1. This fluctuation level is caused by the presence of subthreshold longitudinal modes and mode hopping, leading to the emergence of a noticeable 1/f component in their spectrum. |
