====A9====

==Past:==

Used SiO2 mask to create channels and 2.4mm non-proton exchanged region. 
Proton exchanged 10min, annealed 45min.

==Current:==
prepped with LOR and pmma for writing. 
Written, evaporated, lifted off. 
Success!

This device showed only one mode on the Metricon. We will try re-annealing the device for 20 minutes to see if we can create a second mode.

The device was successfully annealed for 20 minutes.

The Metricon still only detects one mode.

Preliminary testing on T1, T3, T5, T11, T15, T18.  27 nH used on each transducer.

This device I am sure I got in the TE1 mode for blue. I am also now positive that It was the TE2 mode I used for blue for A7.

==Future:==
given to Scott for polishing and testing.
