Abstract
The laser threshold reduction in a spintronic device was discussed. A reduction of the threshold of a semiconductor laser by optically pumping spin-polarized electrons in the gain medium was elaborated. The analysis showed that the polarized electrons coupled selectively to one of two possible lasing light modes which effectively reduced the threshold up to 50% compared to conventional pumping with unpolarized electrons.
