摘要： A mode-locked integrated semiconductor laser has a gain section and an absorption section that are based on quantum-confined active regions. The optical mode(s) in each section can be modeled as occupying a certain cross-sectional area, referred to as the mode cross-section. The mode cross-section in the absorber section is larger in area than the mode cross-section in the gain section, thus reducing the optical power density in the absorber section relative to the gain section. This, in turn, delays saturation of the absorber section until higher optical powers, thus increasing the peak power output of the laser.

摘要： Symmetric quantum dots are embedded in quantum wells. The symmetry is achieved by using slightly off-axis substrates and/or overpressure during the quantum dot growth. The quantum dot structure can be used in a variety of applications, including semiconductor lasers.
