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