Polarization switching in semiconductor lasers driven via injection from an external radiation

Abstract
Switching between transverse electric (TE) and transverse magnetic (TM) polarization states in the output from a semiconductor laser is experimentally obtained through injection locking from an external TM polarized radiation. Switching, which is connected to the loss reduction of the TM modes caused by the injection-locking mechanism, is faster than a few nanoseconds, the resolution limit of our apparatus.
