----
===Projects===
==IRONEAGLE==
  * Create a Aluminum masked based process for writing single samples on the Heidelberg that uses only one deposition of 200nm Al.

==SUPPLYCHAIN==
  * Support the monitor group as they need making sure they always have the devices they need.

==GRATINGS==
  * Create a ESEM driven process that allows us to etch gratings into each device. These have the potential to remove the need for a coupling prism and drop the cost of the modulator to 4% of the current cost.

==ACIDBENCH==
  * Experimentally determine the most efficient form of Proton Exchange from Regular to Dilute PE and Reverse PE.

==SIMULATE==
  * Create a series of simulations that predict the function of a device based on the experimental parameters. We will then be able to "test" devices without even fabricating them.

===Testing Guidelines===
Test every modulator made. Every device should have the following put onto the wiki:
  * Detailed description of the fabrication process.
  * Optical Image of Every Transducer.
  * At least one video of each color using one transducer.
  * At least one full characterization for red, green, and blue with graphs placed on the wiki. Include modulator ID, transducer number, and laser color.
  * //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 be able to create and characterize an 18 Channel Modulator from a slab of X-Cut Lithium Niobate. As such each should strive to become proficient at the following:

  * **Laser safety**
  * Aluminum Deposition in the **E-Beam Evaporator**
  * Aluminum Deposition in the **Thermal Evaporator**
  * Silicon Nitride deposition in **PECVD1** (if continued)
  * SiO2 deposition in **PECVD2**
  * Pattern writing in the **Heidelberg**
  * Using etchants and **acids**
  * Waveguide creation through **Proton Exchange** and **Annealing**
  * Using the **Diesaw**
  * Using the **Polisher**
  * Waveguide measurement in the **Metricon**
  * **Wirebonding** and packaging a device
  * Using the **Network Analyzer for Impedance matching** the breakout board
  * Be able to effectively **Prism Couple**
  * Characterization of devices using the **Characterization Apparatus**

Also strive for a theoretical understanding of the modulators produced. Please read through everything about leaky mode modulators on our wiki's "Publications" page.

===Future Paper Ideas===
  * Linearity of leaky mode interaction
  * Diffraction efficiency comparison between, PE, APE, ADPE, RPE
  * Diffraction efficiency change for y device
