Adaptive Focusing for Ultrafast Laser Internal Structuring of Narrow Bandgap Materials - ADFUN

窄带隙材料（NBM）内部的3D制造具有广泛的应用，例如集成光子学、3D结构制造、中/远红外或THz器件、微流体等。然而，在NBM内部获得3D制造仍然是一个挑战。超短脉冲激光是3D制造的理想工具，但最近的研究表明，由于激光传播过程中的非线性失真，NBM内部存在明显的挑战。该建议解决了使用新的自适应聚焦方法制造3D NBM的困难。新的3D制造能力预计将被开发，以访问嵌入式功能结构内的NBM，这可能会导致新的功能的电子/光子器件。该项目提供了一个独特的知识交流，从不同领域的领先专家，以解决在3D NBM制造的挑战。该研究员不仅将受益于工作的强大科学影响，还将接触不同学科的新技术和合作网络。有专门的培训，以提高研究员的创业，项目管理和提案写作的技能。计划开展一项积极的宣传方案，以提高对该项目的认识，并增加该研究员的知名度。专注的培训和高科学价值将帮助研究员成为世界领先机构的独立研究员。

3D fabrication inside Narrow Bandgap Materials (NBM) has broad applications such as integrated photonics, 3D-structures manufacturing, mid/far-infrared or THz devices, microfluidics, etc. However, it remains a challenge to obtain 3D fabrication inside NBM. An ultrashort pulse laser is an ideal tool for 3D fabrication, yet recent research demonstrates distinct challenges inside NBM due to nonlinear distortions during the laser propagation. This proposal addresses the difficulties in 3D NBM fabrication using a new adaptive focusing approach. New 3D fabrication capabilities are expected to be developed to access embedded functional structures inside the NBMs which may lead to new functions of electronics/photonics devices.This project provides a unique knowledge exchange from leading experts in different fields to solve the challenges in 3D NBM fabrication. The fellow will benefit from not only the strong scientific impact of the work but also exposure to new techniques and collaborative networks in different disciplines. There is dedicated training to enhance the fellow's skills in entrepreneurship, project management, and proposal writing. An active program of dissemination is planned to raise awareness of the project and increase the visibility of the fellow. The dedicated training and high scientific value will help the fellow to become an independent researcher in a world-leading institution.
