E10
Past:
X-cut. NOT PROTON EXCHANGED.
Written with new EO device without a resistor bridge. 3mm wide at spot 30. Only lifted off in center.
Cleaned completely.
RB E10
Current:
Two samples exist with this number one is a Resistor Bridge EO with 200nm of Chrome.
It looks like the following:

Current
The old resistive strips were removed and 50nm of NiCr were put in their place. A 45 min anneal was done at 350°C. As can bee seen pads 1-2 and 3-4 did not connect with the resistive strip.
It now looks like the following:
