英文摘要： External-cavity mode-locked quantum dot lasers with tunable wavelength and repetition rate in the 1.0-1.3 micron band will be studied in this project. Here, intrinsical non-uniformity of size distribution of the self-assembled quantum dots is used to enhancing the bandwidth of the optical gain spectrum. Further more, ultrafast carrier dynamics in quantum dot materials is very suitable for the generation of ultra-short mode-locked pulses. External-cavity mode-locked quantum dot lasers are advantageous both for the wavelength tuning and the repetition rate tuning. In the project, growth of self-assembled quantum dots, optical and structural properties of quantum dot materials, fabrication and characterization of quantum dot gain devices, and construction of external-cavity mode-locked lasers with tunable wavelength and repetition rate, will be studied comprehensively and systemically.
