The monitor is something that I have always wanted to learn more about and I am so happy to be working with it now because of the Senior Project. This is the power supply that we made for it.

==Weird bug of the week==
This is a picture of a burned sample. I placed in DPE for 4.5 hours and took out and let cool down. Then I placed in Acetone and even then I noticed that some residue wasn't coming off.

This is a picture of the completed waveguides. The next step is Dilute Proton Exchange unless it is decided that new aluminum is needed. \\
These last two weeks have been extremely busy and I was only able to complete the RIE and waveguide writing steps of the process. \\

These are the lapping films I want to buy. But I don't know the price and there are way too many of these. Where can I find other things that do this \\

This is a picture of the good grating that I am working on etching into the Lithium Niobate. Do you have any advice on how I can get it to be cleaner? \\

This is an odd happenstance from this week that I do not understand. I used non-inverted, 38% power, with a normal centering(but not automatic) and developed for 30 seconds with MIF 300. I do not understand what happened\\

I am continuing to work on the multi-channel device. No pictures to show yet but fabrication is in process. \\ 

These are the parts that I ordered that arrived this week. \\ 
I was assuming that the polishing pads would have a type of backing that I could take off but it looks like these designs are wrong. Should I order different ones or is there a different way of putting them on?

I am starting to work on a new design for the multi-channel device with 9 sections. This is the design

====20 dB Amplifier Boards====   

These boards are designed for various applications. Drew made the original design and Scott and I worked out a layout for it. Originally I needed them to use with my 9-channel AO device but they can also be used in the monitor as well as other projects in the lab.\\
