Cost-Effective Optical Fiber Curvature Sensor With Ultrahigh Sensitivity Based on Two Microcollapses in Silica Capillary

Cost-Effective Optical Fiber Curvature Sensor With Ultrahigh Sensitivity Based on Two Microcollapses in Silica Capillary

We proposed an optical fiber curvature sensor based on two microcollapses in silica capillary that was spliced between single-mode fibers. Only commercial fiber fusion splicer was needed in the fabrication process. The two microcollapses in the silica capillary can improve the interference effect of...
