Images from the patent. First, showing the 'poling step'

Items 62 are the poling electrodes. Items 38 and 42 are the permanent (RF) electrodes. Poling is done at this step in the manufacturing process to provide better control. Previously, it was done as the last step, after the electrical leads were connected to the permanent electrodes.

This is a later step with the poling electrodes removed:

Then more layers/components are added to complete the modulator, including placing a low refractive index material on each side of the EO polymer to stop light leakage.
In the earlier design, the RF electrodes were on top of the device, with some layers of materials separating them from the EO polymer. Maybe that is what was causing inconsistencies with the poling process.
I annotate the figures since the figures are presented on consecutive pages with the descriptions provided later in the text. Yes, I am that kind of nerd.
