| Abstract: | The effect of random frequency fluctuations due to spontaneous emission and generation-recombination noise on the shape of
the emission line of a semiconductor laser with pseudorandom modulation of the pump current is studied numerically. The roles
of spontaneous emission and chirp modulation in forming the lasing spectrum are separated out. The dependence of the output
spectral characteristics of the laser on the parameters and type of modulation is analyzed. |
