DATA & FILE OVERVIEW
--------------------

This dataset contains:

Figure3.9.xlsx
This contains thickness information of zinc depositions on a 5% MgO:LN wafer, which is then indiffused at 950C for 1h, and the measured effective refractive index values of the 3 supported modes at 532nm for each sample 

--------------------------
METHODOLOGICAL INFORMATION
--------------------------

Description of methods used for collection/generation of data: 
Zinc thickness is a nominal value, it is set by calibrating the time for the zinc deposition.
A Metricon Model 2010 prism coupler was used to measure the effective indices of supported modes at 532nm. Measurements were taken at several different spots for each sample.

Methods for processing the data: 
An average of the effective indices was calculated, the range of the data is given by 2*Err
