Ultrafast spin dynamics in spin-polarized vertical-cavity surface-emitting laser devices

Ultrafast spin dynamics in spin-polarized vertical-cavity surface-emitting laser devices

Spin-polarized lasers offer new encouraging possibilities for future devices. We compare time-resolved luminescence measurements with theoretical models for spin dynamics in spin-polarized lasers and demonstrate ultrafast polarization switching during one short single-mode laser pulse.
