Developing Rare-Earth-Doped Semiconductor Light Sources
Abstract
Studies were performed on the precession of spin polarized electrons in a magnetic field of up to l2T. Even at densities high enough to provide gain and to see lasing, sufficient spin polarization remains for the lasing emission to alternate back and forth between right and left circular polarization as the spins precess. Thus, the vertical-cavity surface-emitting laser emission is locked to the spin precession clock, one example of coherent control.
