title: Intensity discrimination with twisted birefringent optical fibers.
abstract: A theory of intensity-dependent polarization changes in twisted single-mode fibers is presented. The theory includes the effect of twist-induced circular birefringence and shows that twist can enhance the nonlinear transmission of fiber-optic devices that rely on nonlinear birefringence.
