AO/EO

This group has the ability to take any device through the entire design and prototyping cycle.

Task List

• support 18 Channel Modulator Group as necessary

• 8 channel x-cut
• z-cut electrode

• Race between Helios, Heidelberg and ESEM to create a viable product with 100nm feature size
• input gratings
• output gratings

Optogenetics

Every device should have the following put onto the wiki on the sample list:

• Detailed description of the fabrication process.
• Optical Image of every separate part of each device.
• A video of intelligible prism coupling results.
• Full characterizations for red, green, blue as appropriate.
• System Analyzer Smith Charts, SWR Charts, and any other data recorded for each Transducer should be placed in the “groups folder” so that it is available.

Every Group Member should strive to become a fabrication specialist. (Be able to create and characterize any device from any material). As such each should strive to become proficient at the following:

• Cleanroom Training
• Preparing samples to write in any machine (Helios, Heidelberg, ESEM, Aligner)
• Pattern writing in the Heidelberg
• Al, Cr, Ni, NiCr deposition in the E-Beam Evaporator
• Using etchants and acids for patterning and cleaning
• Etching with the RIE Machine
• Using solvents for development and cleaning
• Wirebonding and packaging a device
• Aluminum Deposition in the Thermal Evaporator
• Silicon Nitride deposition in PECVD1 (if continued)
• SiO2 deposition in PECVD2

• Microscopes
• ESEM training, including manipulating write files
• Helios training, including manipulating write files

• Laser safety
• Waveguide measurement in the Metricon
• Be able to effectively Prism Couple
• Characterization of devices using the Characterization Apparatus

• Grey Room
• Using the Diesaw
• Using the Polisher
• Waveguide creation through Proton Exchange and Annealing

• General
• Creating patterns for writing with bitmaps and stream files
• Creating breakout boards using EAGLE
• Gain a theoretical understanding of the modulators, gratings, and other devices produced. See the Publications page.
