It is unknown whether the bone bruise that occurs in connection with acute anterior cruciate ligament (ACL) rupture is causing pain and dysfunction. We followed prospectively 17 patients [10 men, seven women, mean age 28 years (range 23-34)] with acu

The effect of the excitation level on the intensity and width of whispering-gallery-mode (WGM) lines in microdisks with an asymmetric air/GaAs/AlGaO waveguide and an active region containing InAs quantum dots is studied using microphotoluminescence s

The optical properties of InAs /( Al ) GaAs quantum dots (QDs) overgrowth by thin AlAs / InAlAs layers are studied as a function of temperature from 10 to 500 K. The QDs emit at 1.27 μm at room temperature. It is shown that the QD energetic spectrum

980 nm vertical-cavity surface-emitting lasers based on submonolayer growth of quantum dots show clearly open eyes and operate error free with bit error rates better than 10 at 25 and 85degC for 20 Gb/s without current adjustment. The peak differenti

Self-assembled quantum dots (QDs) in double-layer InAs/GaAs structures are studied by resonant photoluminescence and photoluminescence excitation spectroscopy. A weakly correlated (50%) double-layer system with an array of vertically coupled QDs (asy

Accumulated spectral hole burning is demonstrated for self-organized InAs/GaAs quantum dots (QDs) embedded in the space-charge region of a p–i–n diode. In two-color experiments, selective charging of QDs by resonant optical excitation is proved.

Coupling of acoustic and optical phonons to excitons in single InGaAs/GaAs quantum dots is investigated in detail experimentally and theoretically as a function of temperature. For the theoretical description of the luminescence spectrum, including a
