Poling of Planar Silica Waveguides

UV-written planar silica waveguides are poled using two different poling techniques, thermal poling and UV-poling. Thermal poling induces an electro-optic coefficient of 0.067 pm/V. We also demonstrate simultaneous UV-writing and UV-poling. The induced electro-optic effect shows a linear dependence on the poling voltage. No measurable decay in the induced electro-optic effect was detected after 14 months.
