Brief
Based on the source provided, the article demonstrates a compact variable single-mode fiber coupler based on microfibers where twisting two identical microfibers adjusts the coupling ratio from 3.15% to 98.5% by changing the evanescent field interaction length.
Summary
The paper demonstrates a compact, variable single-mode fiber coupler made by twisting two identical microfibers. By adjusting the twist angle, which changes the evanescent field interaction length, the coupling ratio can be widely tuned from 3.15% to 98.5%.
