===Current Projects===

==Acousto-Optic Modulators==
  * support 18 Channel Modulator Group as necessary 

==Electro-Optic Modulators==
  * 8 channel x-cut 
  * z-cut electrode 

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

==Secondary Project:==       
 [[Brain Probe|Optogenetics]]

===Recording Guidelines===
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//.

----
===Skills===
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.
