A monolithically integrated device combines 40 GHz dual mode-locked operation with the wide tuning range (>40nm) of sampled-grating DBR lasers, while further being integrated to an SOA and a potentially high-speed modulator. OCIS codes: (250.5300) Photonic integrated devices; (140.3600) Lasers, tunable; (140.4050) Mode-locked lasers
Fig. 4. a: Optical spectra taken through the tuning-range of the laser; low, center and high wavelength, illustrating a sidemode suppression ratio better than 20dB. (Res. bandwidth ~0.08nm). b: Fiber-coupled output power and center cavity resonance frequency over the wavelength tuning range of the laser.
