====A10====

==Past:==

Used SiO2 mask to create channels and 1.4mm non-proton exchanged region. 
Proton exchanged 10min, annealed 45min.

==Current:==
prepped with LOR and pmma for writing. 
Written, evaporated, lifted off. 
Success! (There is overlap between transducers and waveguide)

This device showed only one mode on the Metricon. We will try re-annealing the device for 30 minutes to see if we can create a second mode.

The device was successfully annealed for 30 minutes.

The Metricon still only detects one mode.

The bump arround 310MHz is an anomaly caused by the interaction between scattered light and the transducers. I have video evidence of this fact. The humps around 550 MHz are the true humps. The same goes for the bump around -40°.
