Abstract:	A bulk-optics, polarization-independent phase shifter for photonic quantum information applications is demonstrated. The device is based on a transverse electro-optic modulator in a Sagnac-type loop containing Faraday rotators. This direction-dependent polarization rotation in the loop is combined with a Mach-Zehnder interferometer to form an optical switch with an on/off contrast of 96 and a switching time of 1.6 ns. We demonstrate that the devices operation maintains any arbitrary polarization state. © 2011 American Institute of Physics.
