Polarization Bistability due to Optical Feedback
P. Belkner, F.‐J. Schütte
Abstract
Abstract An optical ring cavity filled with an isotropic medium is driven externally. Two waves of the same frequency but of different polarization are coupled nonlinearly by a Kerr type interaction. It is theoretically shown that the symmetry of the linear polarized input field may be broken spontaneously. Beyond an intensity threshold the output field gets elliptic polarization. Right and left elliptic states are stable. The system shows polarization bistability.
