New Approach for High Reliability, Low Loss Splicing between Silica and ZBLAN Fibers

Author: Robin Carbonnier and Wenxin Zheng Thursday, July 5, 2018
In the past decade, ZBLAN (ZrF4-BaF2-LaF3-NaF) fibers have drawn increasing interest for laser operations at wavelengths where Fused Silica-based (SiO2) fibers do not perform well. One limitation to the expansion of ZBLAN fiber lasers today is the difficulty to efficiently inject and extract light in/from the guiding medium using SiO2 fibers. Although free space and butt coupling have provided acceptable results, consistent and long lasting physical joints between SiO2 and ZBLAN fibers will allow smaller, cheaper and more robust component manufacturing.
