Polarization control by optical feedback in semiconductor lasers

Control of the polarization state of semiconductor lasers is achieved by placing a polarizer in an external cavity. The TE and TM components of the laser beam are coupled with each other by the polarizer under optical feedback. The experimental results are explained by a coupled-mode model.
