Abstract

This study introduces a machine learning (ML)-assisted framework for optimizing Proportional-Integral-Derivative (PID) coefficients, enabling stable, long-length single crystal fiber (SCF) fabrication via the Laser Heated Pedestal Growth (LHPG) technique. Compared with traditional curve-fitting methods, the proposed ML approach significantly enhances computational efficiency and achieves up to 20dB improvement in prediction accuracy, leading to notable improvements in SCF uniformity and achievable fiber length. The fabricated sapphire SCF demonstrates a length exceeding 3 m and an average diameter of

$150~\mu $

m with fluctuations below

$\pm 3~\mu $

m, validating the effectiveness of the ML model. Additionally, fundamental guidelines for optimizing PID coefficients in LHPG systems are provided. These results offer valuable insights for high-quality SCF fabrication and are expected to facilitate the production of improved fibers suitable for harsh environment sensing applications.

机器学习增强单晶光纤在激光加热基座生长中的制备

本研究介绍了一种机器学习（ML）辅助框架，用于优化比例-积分-导数（PID）系数，通过激光加热基座生长（LHPG）技术实现稳定的长长度单晶光纤（SCF）制造。与传统的曲线拟合方法相比，本文提出的ML方法显著提高了计算效率，预测精度提高了20dB，从而显著改善了SCF均匀性和可实现的光纤长度。制备的蓝宝石SCF长度超过3 m，平均直径为$150~\mu $ m，波动小于$ $ pm 3~\mu $ m，验证了ML模型的有效性。此外，还提供了优化LHPG系统中PID系数的基本准则。这些结果为高质量的SCF制造提供了有价值的见解，并有望促进适用于恶劣环境传感应用的改进纤维的生产。
