Semiconductor micro/nanowire lasers can be used as integrated coherent light sources. Further, they can be extensively applied in various fields, including optical communication, optical computing, sensors, and biological studies. In this study, we review the domestic and international research progress on wavelength tuning and single-mode lasing of the semiconductor micro/nanowire lasers. Moreover, the Bose-Einstein condensation phenomenon of exciton-polariton based on the strong photon-exciton coupling effect is introduced as a new method to develop micro/nanowire lasers with low lasing thresholds. In addition, the operating mechanism of new lasers based on exciton-polariton and new achievements are presented.
