Abstract

We discuss specifically elaborated technique for characterizing the train-average parameters of low-power picosecond optical pulses with the frequency chirp, arranged in high-repetition-frequency trains, in both time and frequency domains. This technique is applied to rather important case of pulse generation when a single-mode semiconductor heterolaser operates in a multi-pulse regime of the active mode-locking. In fact, the trains of optical dissipative solitary pulses, which appear under a double balance between mutually compensating actions of dispersion and nonlinearity as well as gain and optical losses, are under characterization. The presented approach involves the joint Wigner time-frequency distributions, which can be found for those picosecond optical dissipative solitary pulses due to the exploitation of a novel interferometric technique. Practically, the semiconductor InGaAsP/InP-heterolaser generating at the wavelength 1320 nm was exploited during the illustrating experiments carried out and the possibility of evaluating the corresponding joint Wigner time-frequency distributions has been obviously demonstrated.
