Source Data of figure 4c for "Reconfigurable symmetry-broken laser in a symmetricmicrocavity"

1. This "Source Data" folder provides the corresponding experimental data files for figure 4c in the main text, including the figure, the raw data, the processed data, a source file of the figure, etc.<br>2. The "Source Data\raw data" folder includes the experimental results for the output intensity of chiral Raman laser under different linear coupling strengths of the Raman mode, namely the splitting of the doublet. The file name indicates the corresponding linear coupling strength, for example, the "2g_6.7584" file stands for the results with the mode splitting of 6.7584 MHz.<br>The file folder ("2g_***") is loaded with the repeated measurements under the same linear coupling strength. Each data file (data****.txt) contains two collection channels as the binary format from an oscilloscope: the first channel records the output intensity of the counter-clockwise Raman laser and the Raman mode transmission spectrum simultaneously, and the second channel records the output intensity of the clockwise Raman laser.<br>The specific data is the signal on the oscilloscope with the unit of volt, where 100 mV corresponds to the power of 17.379 microwatts for the Raman laser signal. Besides, the signal of the first (second) channel has an offset being 2.8 mV (31.5 mV).<br>3. The dependence of the chiral threshold power of the Raman laser on the Raman mode splitting can be extracted from the raw data and is shown in the "processed data.xlsx", as well as a modified standard deviation in each case. Here the standard deviation is obtained by considering the deviation from the mean value with a small distribution in the threshold region in each measurement. <br><br>1. 本「源数据（Source Data）」文件夹提供了正文中图4c对应的实验数据文件，包含该图原图、原始数据、处理后数据以及该图的源文件等。<br>2. 「源数据（Source Data）原始数据（raw data）」文件夹包含拉曼模式不同线性耦合强度下，手性拉曼激光输出强度的实验结果，即双峰劈裂情况。文件名标注了对应的线性耦合强度，例如"2g_6.7584"文件代表模式劈裂为6.7584 MHz时的测试结果。<br> 「2g_***」文件夹存储了同一线性耦合强度下的多次重复测量结果。每个数据文件（data****.txt）为示波器采集的二进制格式双通道数据：第一通道同时记录逆时针拉曼激光的输出强度与拉曼模式的透射光谱，第二通道记录顺时针拉曼激光的输出强度。<br> 具体数据为示波器采集的电压信号，其中100 mV对应拉曼激光信号的功率为17.379 微瓦。此外，第一（第二）通道的信号偏移量分别为2.8 mV（31.5 mV）。<br>3. 可从原始数据中提取拉曼激光的手性阈值功率随拉曼模式劈裂的变化关系，该结果与每种情况下的修正标准差一同存储于"processed data.xlsx"中。此处的标准差通过考量每次测量中阈值区域内分布较小的均值偏差计算得到。
