Tests 1-2:
A. Test channel width
B. Test number of channels [total width]
Process: Choose optimal setup from tests 1-3, then run tests 4-5.
Tests 3-4:
C. Test interaction length
D. Test reverse proton exchange vs normal
1 June 2016: First device coupled at 342-343 degrees and was subsequently tested. Oscillating the voltage between 20-40 volts yielded two TE spots (modes were TM) that blinked on and off.
Device ID: EOTEST3
Parameters: 2.5um waveguides, 250um total width
Conclusion: This really isn't a great result. None of these devices have coupled very well. We are going to start with a new wafer and run a series of tests with dilute proton exchange to ensure excellent waveguides all the way through.
6 June 2016: New wafer patterned, etched, cut. Wafer contains 24 devices.
Running all tests on these devices.
Parameters:
12um channels-2um channels, designated on device. Total EO width changed to 500um, 250um, 125um, 62.5um. Wafer contains 4 of each type of sample for redundancy purposes.
