Optical information processing using dual state quantum dot lasers: complexity through simplicity

Abstract We review results on the optical injection of dual state InAs quantum dot-based semiconductor lasers. The two states in question are the so-called ground state and first excited state of the laser. This ability to lase from two different energy states is unique amongst semiconductor lasers...
