Abstract :
In this paper we report, for the first time to our knowledge, a dual-wavelength passive mode-locking regime where pulses are generated simultaneously from both ES (lambda=180 nm) and GS (lambda=1263 nm), in a two-section GaAs-based QD laser. This is the widest spectral separation (83 nm) ever observed in a dual-wavelength mode-locked non-vibronic laser. The exploitation of this mode-locked regime could enable a range of applications extending from time-domain spectroscopy, through to optical interconnects, wavelength-division multiplexing and ultrafast optical processing.
