In 1943 V.L. Ginzburg derived a simple and elegant solution to the polarization optics problem for the case where a linear birefringent medium is uniformly twisted along the optical axis. In a torsion-comoving helical coordinate frame, mutually orthogonal polarization eigenmodes of such optical medium are characterized by two ellipses with the electric field vector bypassed in the opposite sense. Current applications of V.L. Ginzburg's theory are reviewed.
