Abstract

We report a dual-wavelength passive mode locking regime where picosecond pulses are generated from both ground (λ = 1263nm) and excited state transitions (λ = 1180nm), in a GaAs-based monolithic two-section quantum-dot laser. Moreover, these results are reproduced by numerical simulations which provide a better insight on the dual-wavelength mode-locked operation.

Fig. 1

Mapping of the different operating regimes observed in this laser. The dashed region corresponds to the dual-wavelength mode-locking regime here described (GSML + ESML). Legend: GSML – ground-state mode-locking; ESML – excited-state mode-locking; GSCW - ground-state continuous wave operation.

Fig. 2
Fig. 2

(a) Optical spectrum and (b) RF spectrum characteristic of the dual-wavelength mode-locked regime, for a reverse bias of 6V and an injection current of 425mA (the red line in a) depicts the Gaussian fit to the ES and GS spectral bands). In the RF spectrum, the observed power difference between GS and ES is a result of the different optical power level and pulse duration for each of the pulse trains, as elucidated in the text.

Autocorrelation traces for (a) pulses generated via GS mode-locking; (b) pulses generated via ES mode-locking (for a reverse bias of 6V and an injection current of 425mA).
