Disorientated optical polarization devices

Opt Lett. 2011 Apr 1;36(7):1125-7. doi: 10.1364/OL.36.001125.

Abstract

By using a pure operatorial (nonmatrix) approach to some of the variable composite polarization devices, we show that for some values of the variable internal parameters, these devices lose their anisotropy. Their principal axes, or more generally their eigenvectors, become undetermined, i.e., in this sense, the anisotropic devices get "disorientated."
