摘要：
A wavelength-tunable mode-locked quantum dot laser using an In As/Ga As quantum-dot gain medium and a discrete semiconductor saturable absorber mirror is demonstrated.A dispersion prism,which has lower optical loss and less spectral narrowing than a blazed grating,is used for wavelength selection and tuning.A wavelength tuning range of 45.5 nm(from1137.3 nm to 1182.8 nm) under 140-m A injection current in the passive mode-locked regime is achieved.The maximum average power of 19 m W is obtained at the 1170.3-nm wavelength,corresponding to the single pulse energy of 36.5 p J.
