# Dataset Description An experiment was performed to characterize a mode converter in an optical fiber at different polarizations. The tunability of the converter at different temperatures (20.62 °C, 35 °C, 50 °C, 65 °C, and 80 °C) was evaluated, revealing a strong dependence of the mode conversion on the output polarization, temperature, and wavelength used. ## Acquisition Parameters and Dataset Overview - **Method**: OptiGUI DataCollector: A graphical user interface for automating the data collecting process in optical and photonics labs doi: 10.1016/j.softx.2023.101521. - **Total Datasets**: 5 - **Images per Dataset**: between 9805 and 10036. - **Total Images**: 49736 images. - **Image Format**: .tiff ## Sample Images Near-field experimental patterns obtained at the output end of the mode converter based on LPFG as a function of the applied temperature and analyzer angle when the laser light at the input end of the device is aligned along to horizontal axis and vertical axis. These results were obtained for a wavelength of 1527 nm, while light is introduced into the mode converter at 0° ![enter image description here][1] ## Image Nomenclature Explanation Nomenclature of the .tiff images in the dataset. Note that the letter in red corresponds to the only elements that change in the file names (input polarization, wavelength, and output polarization). ![enter image description here][2] ## Dataset Objective The datasets aim to train a robust deep learning model for employing a modal decomposition methodology through experimental LP modes. ## Citation Request for the Dataset When utilizing this dataset in your research, we kindly request citing our corresponding research paper.
