GOAL: Design a low-profile, transparent, near-eye holographic display

OBJECTIVE: Vertical and horizontal deflection of light through acousto-optics and electro-optics respectively
  * Celestial: AO/EO deflection from the [[https://www.osapublishing.org/oe/abstract.cfm?uri=oe-25-17-20622|back]] side of the substrate
  * Terrestrial: AO/EO deflection from the bulk edge of the substrate 
  * Telestial: Multichannel EO deflection from the edge of the waveguide

MILESONES and QUESTS:
  - Truncated Mach-Zehnder Interferometer (x-cut lithium niobate)
    - Q1 [[X-cut deflection measurements]]
  - Truncated Mach-Zehnder Interferometer (z-cut lithium niobate)
    - Q2 [[Fiber coupling setup]]
    - Q3 [[Fiber couple light into thin substrate]]
    - Q4 [[Refine diffusion process]] want really low loss in z-cut substrates
        * method looking loss from photograph top streak
        * literature for SPDE low-loss proton exchange 
        * m1 find d param new melt
        * make z-cut strips
        * moving variable temperature
        * moving varialbe is dilution  -->losses in db/cm 5x5 grid (cel) Ter/tel--> (pictures from light inside)
    - Q5 [[Electrodes and EO testing for thin substrate]]
    - Q6 [[Z-cut deflection measurments]]
  - Q7 EO deflection paper

INTERNAL TIMELINE:
  * x-cut TMZI: 5/8/20
  * z-cut TMZI: 6/19/20
  * EO paper: 7/1/20
