Dynamic spectra of pulsed laser diodes and propagation in single-mode fibers

Dynamic statistical properties of pulsed semiconductor lasers are determined using numerical simulation of the rate equations including noise. This includes the average intensity, field correlation at pairs of time instants during the pulse lifetime, and the associated time-varying spectrum. Variation of the coherence time as the pulse rises and drops are determined and frequency chirping is examined. Propagation of such pulses through a single-mode dispersive fiber is investigated, and results are compared to earlier simpler models.
