Optics Express. 2021, volume 29, issue 6, pp. 8531-8541 https://doi.org/10.1364/OE.409527 # Research materials We provide here the data and scripts used to generate the figures in the main document ## Requirements * All codes have been written using *python 3.7* and standard libraries (*numpy*, *matplotlib*, *scipy*). * Note that pathnames work fine for Unix users but might be manually modified for Windows users. ## Data files description All experimental data files are stored in the `./data` folder with `.npy` format, a standard binary file format in NumPy. * `bgg-2p85.npy` and `silica-2p85.npy` contains the experimental data used to generate Fig. 3. * `bgg-2p85-num.npy` contains numerical data used in Fig. 3 (dashed blue line). * `bgg-4mm-exp.npy`/`bgg-4mm-num.npy` and `bgg-5mm-exp.npy`/`bgg-5mm-num.npy` contains the experimental/numerical data used to generate Fig. 4 left and right panels respectively. The `.npy` files are dictionnaries. The key `P_ref` corresponds to the grey curve in Fig. 4a. The keys `P_1_3` and `P_1_4`correspond to the output power in port 3 and port 4 respectively. ## Script files description * Running the python scripts allow to generate the figures presented in the manuscript. The filenames are explicit. * Fig. 4 has been slightly post-edited (add $y$-axis color and a) and b) labels) using Adobe Illustrator software.
