Ultrafast switching of surface emitting semiconductor microlasers,asers. This behaviour will be demonstrated both on a model structure and on a commercially available electrically pumped device, and it will be compared with numerical simulations based on different models.

White light emitting diodes,the phosphor Y.Al.O.:Ce.(4f.) is ideally suited. The optical characteristics of Ce.(4f.) in Y.Al.O.(YAG) are discussed in detail. Possibilities to “tune” the white color by various substitutions in the garnet lattice are shortly outlined.

Augmented Reality Using ARKit and OpenCV,I quantum wells and confined in semiconductor nanocrystals, and exciton polaritons in microcavities with embedded quantum wells or gratings of quantum wires. The exchange and Zeeman splittings are shown to be extremely sensitive to the structure geometry and the shape of the exciton envelope function.

Leszek J. Chmielewski,Arkadiusz Orłowski non magnetic metal interlayers. As in the GMR systems the coupling strength oscillates with increasing thickness of the interlayers. The oscillation period depends on the material of the interlayers.

Leszek J. Chmielewski,Arkadiusz Orłowski. The time evolution of the damping rate follows that of the electron temperature, showing that the damping rate is strongly influenced by transient variations in the electron scattering rate. The dependence of the damping rate on the excitation energy shows evidence for fast relaxation of the optically generated d-band holes.
