In this article, an optical switch utilizes a birefringent device to cause orthogonally polarized components of an arbitrarily polarized incident light beam to propagate along separate paths.Abstract:
An optical switch utilizes a birefringent device to cause orthogonally polarized components of an arbitrarily polarized incident light beam to propagate along separate paths. A polarization rotator is positioned in one path to rotate the polarization of the light beam propagating therealong to that of the light beam in the other path. The two paths are simultaneously deflected to selected parallel paths in accordance with the switching desired. A second polarization rotator reestablishes the initial polarization and the beams are recombined by a second birefringent device to emerge from the selected output terminal as an arbitrarily polarized light.read more

TL;DR: In this article, a bidirectional optical space switch for selectively coupling an input signal to a selected output is proposed, which consists of two arrays of inputs (1, 8, 2, 3, 4, 5, 6), polarising beam splitters (2, 4), and a matrix of cells (3), each of which is selectively capable of varying the polarisation state of light passing through it in response to an applied control signal.
