    Nonlinear Optics and Saturation Behavior of Quantum Dot Samples Under Continuous Wave Driving

    The nonlinear optical response of self-assembled quantum dots (QD) is relevant to the application of QD-based devices in nonlinear optics, all-optical switching, slow light, and self-organization. Theoretical ...

    Tunable, narrow-band light source in the 1.25 μm region based on broad-area quantum dot lasers with feedback

    The coherence of broad-area laser diodes with quantum dot gain medium is improved by frequency-selective feedback. A linewidth of 5–10 GHz at power levels of 10–140 mW is achieved in the wavelength region arou...
