Patent

CA 2419313

Broadband polarization transformation devices of various constructions are provided. The devices of the invention include a plurality of polarization switching elements that are either wavelength insensitive or used only in a wavelength insensitive manner. Preferably, 90° or 45° twisted liquid crystal cells which are electrically switchable and achromatic birefringent elements (such as Fresnel Rhombs) are used. In a particularly advantageous embodiment, the device is composed of, consecutively, a 90°TLC cell, a 45°TLC cell, a Fresnel Rhomb and an additionnal 45° TLC cell, allowing an initially linearly polarized light beam to be switched between the output polarization states p, s, .sigma., -.sigma., 45° and -45° depending on the application of voltages on the TLC cells.
