=====F1===== The following circuit was used in testing these devices: {{:samples:eo_circuit_driver.png?800|}} This is the first EO device that uses variable path lengths instead of Resistor Bridges. I will call these VPL EO devices. It has 200nm Al that was patterned with a design by Christopher. It was then Proton Exchanged with the new proton exchange parameters 15min with a 45min Anneal at 375°C. Then 200nm Aluminum was used to create the connection strips.
