Abstract

Experimental and theoretical studies on polarization bistability or switching in laser diodes have been investigated[1]-[3]. Using a tensilely strained quantum-well structure, highly efficient polarization switching has been demonstrated in multi-electrode Fabry-Perot lasers[4]. For these devices, however, the switching has been observed with multi longitudinal mode operation, which are not suitable for optical frequency division multiplexing systems.
