Since the first observtion of ground-state lasing in quantum wire lasers, many-body electron interctions and lasing mechanism in one-dimensional (1-D) wire lasers became the central issues of interest. Questions about existence of band-gap renormalization and contribution of excitons to gain in lasing is hotly argued but remains unsolved for about a decade. This paper studies these problems by means of recently achieved highly-uniform T-shaped quantum wires of 14 nm x 6 nm cross-sectional size and lasers containing these T-wires.
