Abstract: Lead halide perovskite nanocrystals (NCs) were recently found to exhibit extraordinary optical amplification properties. The great majority of such studies implemented ultrashort photon pulses in the femtosecond regime to initiate the stimulated emission process. Yet… read more here.

Abstract: We observed strikingly different first reflection dynamics of two counter-propagating laser beams passing through a wedge-shaped C60-doped liquid crystal cell sandwiched between two ZnSe-coated ITO glass plates without applied electric field, suggesting a strong subwavelength… read more here.

Abstract: Hollow core optical fibers are normally passive light transport components. In contrast, within this Letter, we numerically investigate the possibility of using them as optical amplifiers, through the adoption of a novel fiber structure. We… read more here.
