Abstract:Room-temperature lasing based on low-dimensional GaAs nanowires (NWs) is one of the most critical and challenging issues in realizing near-infrared lasers for nanophotonics. In this article, the random lasing characteristics based on GaAs NW arrays have been discussed theoretically. According to the simulation, GaAs/AlGaAs core−shell NWs with an optimal diameter, density, and Al content in the shell have been grown. Systematic morphological and optical characterizations were carried out. It is found that the G… Show more
Controlling the random lasing action from disordered media is important to obtain customizable lasers with unprecedented properties. In this manuscript, systematic investigations on the random scattering based on GaAs/AlGaAs axial...
