Dataset and Analysis Code for "Collective Strong Coupling of Thermal Atoms to Integrated Microring Resonators"
Description
This repository contains the experimental data and MATLAB analysis code associated with the study **“Collective Strong Coupling of Thermal Atoms to Integrated Microring Resonators.”**
The dataset includes transmission spectra measured at different rubidium reservoir temperatures and probe powers, fitted bare-cavity and split-spectrum parameters, background-referenced 2D transmission maps, reference rubidium transition line positions, and MATLAB scripts used for fitting, analysis, and figure generation.
Measurement folders are named in the form `Tcell120_TresXX_power`, where `Tcell120` denotes a cell-body temperature of 120 °C, `TresXX` gives the rubidium reservoir temperature in °C, and the final entry indicates the probe power. Each measurement folder contains split-spectrum data near zero cavity detuning in `real_Rb85F2_#` subfolders, bare-cavity spectra in `BareResonance_#` subfolders, a background-referenced 2D colormap saved as `2D_colormap_movmean_BGreferenced.fig`, and a reference line file `Rb_lines_position.csv`.
The `slice.mat` and `slice.fig` files stored in the spectral subfolders are derived directly from the background-referenced 2D colormap and represent essentially raw experimental data after background referencing. The only processing applied is the removal of a weak parasitic cavity resonance background. No further transformation of the spectral data is applied.
The folder `DataProcessingCodes` contains the main MATLAB scripts used to reproduce the analysis and selected figures presented in the associated publication.
This repository contains only the data and code prepared by Xiaoyu Cheng for the reported results. If you use these materials, please cite both the associated paper and the DOI of this dataset.

A detailed model of the susceptibility is developed which takes into account the absolute linestrengths of the allowed electric dipole transitions and the motion of the atoms parallel to the probe beam. All transitions from both hyperfine levels of the ground term of both isotopes are incorporated. The absorption and refractive index as a function of frequency are expressed in terms of the complementary error function. The absolute absorption profiles are compared with experiment, and are found to be in excellent agreement provided a sufficiently weak probe beam with an intensity under one-thousandth of the saturation intensity is used. The importance of hyperfine pumping for open transitions is discussed in the context of achieving the weak-probe limit. Theory and experiment show excellent agreement, with an rms error better than 0.2% for the D2 line at 16.5°C. {\textcopyright} 2008 IOP Publishing Ltd.}, annote = {This paper gives the explanation and the Rb D2 center of mass frequency reference of Ralf Ritter's thesis in which he simulate the Rb absorption with the coupling to the ring cavity.
