Squeezing data from Demonstration of a Squeezed Light Source on Thin-Film Lithium Niobate with Modal Phase Matching

<p dir="ltr">This repository contains data and a script to plot the data for the paper by Arge et al. (2024), titled "Demonstration of a Squeezed Light Source on Thin-Film Lithium Niobate with Modal Phase Matching". Included is a readme file, raw data for squeezing measurements, saved as CSV files. One folder of raw data for measurements at different frequencies and one folder for different powers. In addition there is a script titled "sqzEstimatorModified.py" that makes the plots seen in the publication.</p><p dir="ltr">The data is a series of zero-span measurements from a RF signal analyser, measuring the AC signal from a homodyne detector in an optical setup.</p><h4><b>Files included</b></h4><ol><li>Folder titled "E2 - freq plot".
