This article provides an overview of the physics and technologies behind the rapid progress of miniaturization of semiconductor lasers, in particular the quantum wire lasers based on onedimensional nanoscale optical gain media. Since the first report of lasing in quantum wires by Kapon and his co-workers [1], quantum wire lasers have evolved from .microlasers. in which the onedimensional nanostructure is embedded in a micron size optical cavity, to .nanolasers. in which, as we recently demonstrated [2], the material gain and optical feedback are simultaneously achieved by individual nanoscale quantum wires. One-dimensional semiconductor fabrication technologies based on nanoscale lithography, selforganization, selective growth, and chemical synthesis will be reviewed along with recent advances of quantum wire lasers built upon each of these fabrication technologies.
