A first electrode (48a) is attached to a first end of each of the modulator sites and a second electrode (48b) is attached to a second end of each of the modulator sites and each of the electrode pairs establishes a field in the poled regions of the modulator sites which causes a phase shift in polarized light incident on the modulator.
