Semiconducting nanowires (NW) have emerged as promising nanoscale materials for new integrated optoelectronic and photonic device technologies, such as NW-based coherent light sources and detectors. In particular, NW-lasers built from III-V semiconductors provide unprecedented functionalities in the monolithic integration and their ultrafast gain dynamics which rely critically on the carrier properties. To advance this field, this project aims to investigate the hitherto unexplored interplay between ultrafast gain properties, i.e., temporal and phase coherent properties of NW-lasers, and the microscopic mechanisms which govern carrier dynamics. Hereby, we will perform a theoretical investigation, using 3D-transient modelling schemes and electro-optical simulations correlated to experimental observations of the carrier lifetime in different regimes of lasing operation.
