Abstract

This paper focuses on the utilization of quartz optical fibers as a foundational material for the miniaturization and integration of various optical paths and components into a single fiber, aiming to construct functional three-dimensional optical devices. It outlines the fundamental concepts and methodologies involved in creating such fiber-based integrated systems.

Key technologies and implementation strategies for realizing three-dimensional optical devices are systematically reviewed. Furthermore, the paper elaborates on approaches to enhance the functionality of these fiber devices through laser microprocessing and material integration techniques. These advancements offer compact and integrated solutions for applications in optical fiber communication and sensing.

Finally, from the perspective of facilitating scientific experiments on the light-matter interaction, the infinite possibilities of constructing "lab on/in optical fiber" were prospected. From the perspective of health and medical application demands, the clinical value and development potential of the new multifunctional optical fiber in the field of minimally invasive interventional surgery were explored.
