title: Photonic phase shifters based on a vector-sum technique with polarization-maintaining fibers.
abstract: We propose and demonstrate a photonic phase shifter based a on vector-sum technique that uses polarization-maintaining fibers (PMFs). We achieved a continuous and full phase shift up to 2pi at 30.48 GHz by controlling the polarization state of the light injected into two pieces of PMF of different lengths and applying two different modulator bias voltages.
