Abstract
Successive waveguide regions in a birefringent waveguide host electric fields oriented transverse to any optical wave propagated through the waveguide. A scheme of cascaded electrodes biased by voltage(s) applied to the electrodes dictate instantaneous field polarity. Cascaded electrodes are sited in nonopposed, noninterleaved relation on opposite sides of a long electrode partially overlapping the waveguide.
