单晶光纤生长技术研究
Growth Technology of Single-Crystal Fibers
摘要
Abstract
As a quasi-one-dimensional material that combines the excellent physical and chemical properties of crystals with the high specific surface area and optical waveguide characteristics of optical fibers,single-crystal fibers hold broad application prospects in fields such as high-power lasers,mid-infrared lasers,radiation detection,and high-temperature sensing.This paper provides a systematic review of the principles,technical characteristics,and research progress of the edge-defined film-fed growth method,the micro-pull-down method,the laser-heated pedestal growth method,and other novel growth techniques.The edge-defined film-fed growth method enables the high-throughput simultaneous growth of hundreds of optical fibers;the micro-pull-down method has been extended to eutectic,metallic,and spring-shaped irregular crystals;the laser-heated pedestal growth method has successfully produced ultra-fine single-crystal optical fibers over 50 m long with a diameter of only 16 µm;the multi-microchannel crucible method has enabled high-throughput fabrication of fluoride optical fibers;the aqueous solution method,meanwhile,provides a low-temperature growth pathway for organic and thermosensitive single-crystal optical fibers,among other applications.Finally,it summarizes the technical challenges and future directions for each method,offering a reference for the preparation and application of single-crystal fibers.关键词
